Abstract
It was found that a single-dose immunization of mice with Yersinia pseudotuberculosis porins OmpF and OmpC causes development of pathological changes in the deep layers of cerebral cortex characterized by dystrophic changes in the cells against the background of the increasing titer of specific antibodies. At the same time, the increased level of caspase-3 expression is observed in the neurons, which indicates induction of proapoptotic signaling pathways. The obtained results indicate potential ability of nonspecific pore-forming proteins of the outer membrane of Gram-negative bacteria to initiate development of degenerative changes in brain cells.

Abstract
Introduction. Study of features for interacting antigen-antibody system is of great importance for developing new modern tools for diagnostics and therapy of infectious diseases. In this regard, it is of great interest to study the rupture force between bacterial antigens and antibodies using modern biophysical methods including optical trapping. The importance of surface antigens in the immunochemical activity of Yersinia pseudotuberculosis assessed by such method has not been evaluated yet. In this work we examined an opportunity to evaluate the interaction of hydrophobic Y. pseudotuberculosis porins OmpF and OmpC with specific antibodies using optical trapping method. Materials and methods. Polystyrene microspheres (d = 1 m) were coated by passive adhesion with purified preparations of OmpF and OmpC porins; microsphere sensitization was verified by enzyme immunoassay. Antibodies from mouse sera were adsorbed onto the glass surface by chemical linking. The rupture force in the porins-antibodies system was determined using a laser trap according to the previously developed algorithm. Results. Using a model system including polystyrene microspheres sensitized with the proteins and aminated glass substrate coated with immune or nonimmune serum, significant differences in binding strength of OmpF and OmpC porins to homologous immune versus nonimmune sera were detected. The average forces of interaction with immune sera was 60 pN for OmpF microspheres (control 40 pN) and 69 pN for OmpC microspheres (control 49 pN). The proportion of irreversible substrate binding of the microspheres coated by the antigens to the treated with immune vs. non-immune sera was significantly higher. The results of assessing the average interaction force, as well as the predominance of the proportion of irreversible binding of antigen-coated microspheres with sera-treated substrates, indicates that specific interactions contribute significantly to the force of interaction. The aforementioned method can be used to evaluate the forces of intermolecular interaction in similar model systems using other microbial antigens.

Abstract
The recombinant OmpF porin of Yersinia pseudotuberculosis as a model of transmembrane protein of the β-barrel structural family was used to study low growth temperature effect on the structure of the produced inclusion bodies (IBs). This porin showed a very low expression level in E. coli at a growth temperature below optimal 37 °C. The introduction of a N-terminal hexahistidine tag into the mature porin molecule significantly increased the biosynthesis of the protein at low cultivation temperatures. The recombinant His-tagged porin (rOmpF-His) was expressed in E. coli at 30 and 18 °C as inclusion bodies (IB-30 and IB-18). The properties and structural organization of IBs, as well as the structure of rOmpF-His solubilized from the IBs with urea and SDS, were studied using turbidimetry, electron microscopy, dynamic light scattering, optical spectroscopy, and amyloid-specific dyes. IB-18, in comparison with IB-30, has a higher solubility in denaturants, suggesting a difference between IBs in the conformation of the associated polypeptide chains. The spectroscopic analysis revealed that rOmpF-His IBs have a high content of secondary structure with a tertiary-structure elements, including a native-like conformation, the proportion of which in IB-18 is higher than in IB-30. Solubilization of the porin from IBs is accompanied by a modification of its secondary structure. The studied IBs also contain amyloid-like structures. The results obtained in this study expand our knowledge of the structural organization of IBs formed by proteins of different structural classes and also have a contribution into the new approaches development of producing functionally active recombinant membrane proteins.

Abstract
The main limitation for practical implementation of quantum dots-based sensors and biosensors is the possible contamination of sensing media with quantum dots (QDs) moved out from the sensor structure, being critical for living systems measurements. Numerous efforts have addressed the challenge of pre-synthesized QDs incorporation into porous matrix provide, on the one hand, proper fixation of quantum dots in its volume and preserving a free analyte transfer from the sensing media to them - on the other hand. Here, we propose an alternative insight into this problem. Instead of using preliminary synthesized particles for doping a matrix, we have in situ synthesized cadmium sulfide QDs in porous biopolymeric matrices, both in an aqueous solution and on a mica substrate. The proposed technique allows obtaining QDs in a matrix acting simultaneously as a ligand passivating surface defects and preventing QDs aggregation. The conjugates were used as a photoluminescence sensor for the metal ions and glutathione detection in an aqueous media. Different kinds of sensor responses have been found depending on the analyte nature. Zinc ions' presence initiates the intraband QDs emission increases due to the reduction of non-radiative processes. The presence of copper ions, in contrast, leads to a gradual photoluminescence decrease due to the formation of the non-luminescent copper-based alloy in the QDs structure. Finally, the presence of glutathione initiates a ligand exchange process followed by some QDs surface treatment enhancing defect-related photoluminescence. As a result, three different kinds of sensor responses for three analytes allow claiming development of a new selective QD-based sensor suitable for biomedical applications.

Abstract
Recombinant porin OmpF (an integral protein of bacterial outer membrane) from Yersinia pseudotuberculosis was synthesized in Escherichia coli cells as inclusion bodies. By combining the methods of anion-exchange and gel filtration chromatographies, recombinant OmpF (rOmpF) was isolated as an individual protein in its denatured state, and its characteristic properties (molecular mass, N-terminal amino acid sequence, and hydrodynamic radius of the protein in 8 M urea solution) were determined. According to the data of gel filtration, dynamic light scattering, optical spectroscopy, and binding of the hydrophobic fluorescent probe 8-anilino-1-naphthalenesulfonic acid, the rOmpF is fully unfolded in 8 M urea and exists in random coil conformation. In aqueous solutions, rOmpF undergoes conformational changes, reversible self-association, and aggregation. When transferred from 8 M urea into water, PBS (containing 0.15 M NaCl, pH 7.4), or buffer containing 0.8 M urea (pH 8.0), fully unfolded rOmpF forms relatively compact monomeric intermediates prone to self-association with formation of multimers. The oligomeric intermediates have high content of native protein-like secondary structure and pronounced tertiary structure. In acidic media (pH 5.0, close to the protein isoelectric point), rOmpF undergoes rapid irreversible aggregation. Therefore, we found that medium composition significantly affects both porin folding and processes of its self-association and aggregation.

Abstract
Site-directed mutagenesis allows elucidation of the basic principles of the porin-driven membrane permeability and opens the possibility for the modulation of functional states of porin channels. The review is aimed to show the advantages of using mutant and chemically modified porins for obtaining detailed information about molecular mechanisms that underlie the non-specific transmembrane diffusion. We summarized data regarding the effects of the point substitutions and the external loop deletions on electrophysiological properties of general porins. The influence of charges inside the pore eyelet and the roles of external loops in ion conductance, ion selectivity, and voltage gating were described.

Abstract
To gain a mechanistic insight in the functioning of the OmpF-like porin from Yersinia pseudotuberculosis (YOmpF), we compared the effect of pH variation on the ion channel activity of the protein in planar lipid bilayers and its binding to lipid membranes. The behavior of YOmpF channels upon acidification was similar to that previously described for Escherichia coli OmpF. In particular, a decrease in pH of the bathing solution resulted in a substantial reduction of YOmpF single channel conductance, accompanied by the emergence of subconductance states. Similar subconductance substates were elicited by the addition of lysophosphatidylcholine. This observation, made with porin channels for the first time, pointed to the relevance of lipid-protein interactions, in particular, the lipid curvature stress, to the appearance of subconductance states at acidic pH. Binding of YOmpF to membranes displayed rather modest dependence on pH, whereas the channel-forming potency of the protein tremendously decreased upon acidification.

Abstract
Lysophosphatidyletnolamine (LPE) is one of enigmatic lipids of bacteria. It is generated from major membrane lipid - phosphatidylethanolamine at severe changes of the bacterial growth conditions. Accumulation of this phospholipid in cells of Gram-negative enterobacterium Yersinia pseudotuberculosis results in the enhanced thermostability of OmpF-like porin (YOmpF) from the same bacteria. The respective integral conformational rearrangements may disturb the channel permeability of protein under stress conditions. However, role of fatty acid composition of LPE in this effect remained unclear. Present work demonstrated that the level of unsaturated LPE is 3.5 times higher than saturated one in total LPE of bacterial cells exposed to stress (phenol treatment). Unsaturated 1-oleoyl-2-hydroxy-sn-glycero-3-phosphoethanolamine (MOPE) and saturated LPE 1-palmitoyl-2- hydroxy-sn-glycero-3-phosphoethanolamine (MPPE) oppositely affect the conformation of YOmpF. MOPE increases the protein thermal stability due to more dense packing of monomers in porin and preserves its trimeric form at elevated temperature, while MPPE weakens the contact between monomers and promotes dissociation of the protein.

Abstract
The purpose of the study was to compare the expression of two Yersinia pseudotuberculosis proteins, wild-type porin OmpY and the mutant porin OmpY designated as OmpY-Q having the uncharged amino acid residue Gln instead of positively charged Arg at the penultimate position in the same heterologous host. According to the literature, a similar substitution (Lys to Gln) of the penultimate amino acid residue in Neisseria meningitidis porin PorA drastically improved the assembly of the protein in the E. coli outer membrane in vivo. Site-directed mutagenesis was used to replace Arg by Gln (R338Q) in OmpY, and the conditions for optimal expression and maturation of OmpY-Q were selected. It was found that the growth rates of E. coli strains producing OmpY and OmpY-Q and the expression levels of the porins were approximately equal. Comparative analysis of recombinant OmpY and OmpY-Q did not show significant differences in structure, antigenic, and functional properties of the porins, or any noticeable effect of the R338Q substitution in OmpY on its assembly in the E. coli outer membrane in vivo. The probable causes of discrepancies between our results and the previous data on porin PorA are discussed considering the known mechanisms of biogenesis of porins at the periplasmic stage.

Abstract
A study of the influence of exogenous factors on the immunochemical activity of the bacterium Yersinia pseudotuberculosis and lipopolysaccharide preparations isolated from bacteria was performed using monoclonal antibodies. It was shown that the hybridomas that were obtained in this work produce antibodies against different and, most likely, species-specific epitopes associated with lipopolysaccharide O side chains. The antibody concentrations produced increased with a decrease in the temperature, at which the bacteria were cultivated. An inhibitory effect of proteinase K, pepsin, and trypsin on the immunochemical activity of bacterial cells, determined using a solid-phase enzyme immunoassay, was demonstrated. Treatment with sodium periodate showed no uniform effect on the reactions between monoclonal antibodies and antigens (lipopolysaccharides and microbial cells), as adjudged by an immunoassay, which is most likely a consequence of the different localization of lipopolysaccharide epitopes recognized by the antibodies from four hybridomas.

Abstract
OmpC-like porin was isolated from the outer membrane (OM) of Yersinia enterocolitica cultured at 37°C (the "warm" variant) and its physicochemical and functional properties were studied. The amino acid sequence of OmpC porin was established, and the primary structure and transmembrane topology of this protein were analyzed in comparison with the OmpF porin isolated from Y. enterocolitica cultured at 6°C (the "cold" variant). Both porins of Y. enterocolitica had a high homology degree (65%) between themselves and with OmpC and OmpF porins from OM of Escherichia coli (58 and 76% homology, respectively). The secondary structure of OmpC and OmpF porins from OM of Y. enterocolitica consists of 16 β-strands connected by short "periplasmic" and longer "extracellular" loops with disordered structure, according to the topological model developed for porins of E. coli. The molecular structures of OmpC and OmpF porins of Y. enterocolitica have significant differences in the structure of the "extracellular" loops and in the position of one of three tryptophan residues. Using the bilayer lipid membrane (BLM) technique, pores formed by OmpC porin of Y. enterocolitica were shown to differ in electrophysiological characteristics from channels of OmpF protein of this microorganism. The isolated OmpC porin reconstructed into BLM displayed functional plasticity similarly to OmpF protein and nonspecific porins of other enterobacteria. The conductivity level of the channels formed by this protein in the BLM was regulated by value of the applied potential.

Abstract
Gram-negative bacteria are enveloped by two membranes, the inner (cytoplasmic) (CM) and the outer (OM). The majority of integral outer membrane proteins are arranged in β-barrels of cylindrical shape composed of amphipathic antiparallel β-strands. In bacteria, β-barrel proteins function as water-filled pores, active transporters, enzymes, receptors, and structural proteins. Proteins of bacterial OM are synthesized in the cytoplasm as unfolded polypeptides with an N-terminal sequence that marks them for transport across the CM. Precursors of membrane proteins move through the aqueous medium of the cytosol and periplasm under the protection of chaperones (SecB, Skp, SurA, and DegP), then cross the CM via the Sec system composed of a polypeptide-conducting channel (SecYEG) and ATPase (SecA), the latter providing the energy for the translocation of the pre-protein. Pre-protein folding and incorporation in the OM require the participation of the Bam-complex, probably without the use of energy. This review summarizes current data on the biogenesis of the β-barrel proteins of bacterial OM. Data on the structure of the proteins included in the multicomponent system for delivery of the OM proteins to their destination in the cell and on their complexes with partners, including pre-proteins, are presented. Molecular models constructed on the basis of structural, genetic, and biochemical studies that describe the mechanisms of β-barrel protein assembly by this molecular transport machinery are also considered.

Abstract
The tubular immunostimulating complex (TI-complex) is a novel nanoparticulate antigen delivery system consisting of cholesterol, triterpene glycoside cucumarioside A(2)-2, and glycolipid monogalactosyldiacylglycerol (MGDG) isolated from marine macrophytes. MGDG is crucial for the formation of a lipid matrix for the protein antigen incorporated in TI-complexes. Fatty acid composition and the physical state of this glycolipid depend on the taxonomic position of marine macrophytes. Therefore, the aim of the present work was to study the capacity of MGDGs, isolated from five species of marine macrophytes, to influence conformation and to enhance immunogenicity of porin from Yersinia pseudotuberculosis (YOmpF) as a model antigen of subunit vaccine based on TI-complexes. The trimeric porin was chosen for these experiments, because it was approximately two times more immunogenic than monomeric porin incorporated in TI-complexes. Immunization of mice with YOmpF within TI-complexes, comprised of different MGDGs, revealed a dependence of the immunostimulating effect of TI-complexes on the microvicosity of this glycolipid. TI-complexes comprising MGDGs from Sargassum pallidum and Ulva fenestrata with medium microviscosity induced maximal levels of anti-porin antibodies (four times higher when compared with those induced by pure porin). The adjuvant effect of TI-complexes based on other MGDGs varied by 2.8, 2.3 and 1.3 times for TI-complexes comprised of MGDGs from Zostera marina, Ahnfeltia tobuchiensis, and Laminaria japonica, respectively. MGDGs are also able to influence cytokine mechanisms of immunological regulation. DSC and spectroscopic studies showed that maximal immunostimulating effect of TI-complexes correlated with a moderate stabilizing influence of MGDGs from S. pallidum and U. fenestrata on the conformation of porin. The results obtained suggest lipid "nanofluidics" as a novel strategy for optimizing the immune response to protein antigens within lipid particulate systems.

Abstract
A novel OmpY porin was predicted based on the Yersinia pseudotuberculosis genome analysis. Whereas it has the different genomic annotation such as "outer membrane protein N" (ABS46310.1) in str. IP 31758 or "outer membrane protein C2, porin" (YP_070481.1) in str. IP32953, it might be warranted to rename the OmpN/OmpC2 to OmpY, "outer membrane protein Y", where letter "Y" pertained to Yersinia. Both phylogenetic analysis and genomic localization clearly support that the OmpY porin belongs to a new group of general bacterial porins. The recombinant OmpY protein with its signal sequence was overexpressed in porin-deficient Escherichia coli strain. The mature rOmpY was shown to insert into outer membrane as a trimer. The OmpY porin, isolated from the outer membrane, was studied employing spectroscopic, electrophoretic and bilayer lipid membranes techniques. The far UV CD spectrum of rOmpY was essentially identical to that of Y. pseudotuberculosis OmpF. The near UV CD spectrum of rOmpY was weaker and smoother than that of OmpF. The rOmpY single-channel conductance was 180 ± 20 pS in 0.1 M NaCl and was lower than that of the OmpF porin. As was shown by electrophoretic and bilayer lipid membrane experiments, the rOmpY trimers were less thermostable than the OmpF trimers. The porins differed in the trimer-monomer transition temperature by about 20°C. The three-dimensional structural models of the Y. pseudotuberculosis OmpY and OmpF trimers were generated and the intra- and intermonomeric interactions stabilizing the porins were investigated. The difference in the thermal stability of OmpY and OmpF trimers was established to correlate with the difference in intermonomeric polar contacts.

Abstract
AIM Evaluation of immunogenic and protective properties of constructs based on subunit porin antigen from Yersinia pseudotuberculosis, immunostimulating complexes (ISCOM) and tubular immunostimulating (TI) complexes. MATERIALS AND METHODS Porin antibodies and blood serum cytokines were determined by using EIA. Porin-specific cell immunity was evaluated by DTH reaction inflammation index. Protective activity of porin formulations was determined by measuring specific gravity of animals surviving Yersinia pseudotuberculosis lethal challenge. RESULTS Porin in TI complexes develops higher immunogenicity when compared with individual protein or protein with complete Freunds adjuvant. Porin in TI complexes develops higher protective activity, inhibits interferon synthesis in mice. Incorporation of porin into TI complexes results in neutralization of porin suppressive activity against DTH mechanisms and interferon system. CONCLUSION TI complexes may be used as perspective carriers for bacterial antigens. TI complexes have adjuvant properties and can provide protective properties to porin vaccine constructs.

Abstract
Multiple antigenic peptides (MAPs), a sequence which include common antigenic epitopes of outer membrane porins (OM) bacteria of the genus Yersinia (Y. pseudotuberculosis, Y. enterocolitica, Y. pestis), pathogenic for humans have been synthesized. After immunization of BALB/c mice the antiserum to the peptide have been obtained. With the help of ELISA we showed that these sera interact with porins isolated from OM pathogenic Yersinia, and MAP interact with antibodies in sera from rabbits immunized with individual porins, and with antibodies in sera of patients with intestinal yersiniosis and pseudotuberculosis.

Abstract
We studied the capacity of outer membrane pore-forming recombinant protein from Yersinia pseudotuberculosis to initiate the development of immune response in CBA mice. Immunization with the recombinant protein induces the production of IgG antibodies with and without adjuvants. High-avidity immune serum was obtained as a result of immunization. Bactericidal activity of peritoneal macrophages from mice immunized with recombinant protein was significantly higher than that of intact mouse macrophages. The use of recombinant porin instead of native porin as the antigen in enzyme immunoassay system for the diagnosis of acute and secondary focal pseudotuberculosis does not reduce the efficiency of detection of specific antibodies in the sera of patients.

Abstract
A novel antigen carrier has been formulated on the basis of a cucumarioside-A2-2 triterpene glycoside (CD) complex with cholesterol and monogalactosyldiacylglycerol from Ahnfeltia tobuchiensis (MGDG(At)) and Ulva fenestrate (MGDG(Uf)). Morphological and immunostimulative characteristics of the carrier were studied. Electron microscopy experiments demonstrated the formation of homogeneous tubular structures in a mixture of CD, cholesterol, and MGDG in molar ratio of 1:2:3. In animals immunized by the carrier bearing pore forming protein monomer of pseudotuberculosis agent CD and MGDG synergically affected synthesis of specific antibodies, interleukin-2, and gamma-interferon and delayed hypersensitivity reaction when compared to Freund's complete adjuvant or to immunostimulatory complexes between Quillaja saponaria saponins and phosphatidylcholine from egg yolk. The immunostimulatory effect depends upon the composition of polyunsaturated fatty acids of MGDG. The new tubular adjuvant carrier is a competitive adjuvant, as it includes CD obtained from far-eastern sea cucumber commercial species Cucumaria japonica, and MGDG from seaweed.

Abstract
The encoding sequence of the pore-forming OmpF-like protein from the Yersinia pseudotuberculosis outer membrane was cloned and expressed in Escherichia coli cells. Conditions were selected for isolation and refolding of recombinant monomer and porin trimer. Their spatial structures were characterized by the intrinsic protein fluorescence and CD spectroscopy. It was shown that the recombinant porins are similar in the composition of secondary structure elements to the isolated porins, but have a considerably less compact tertiary structure. The pore-forming activities of the recombinant proteins are similar to those of Y. pseudotuberculosis native porins.

Abstract
The molecular organization and functional activity of porins isolated from the outer membrane (OM) of the Yersinia enterocolitica and three phylogenetically close nonpathogenic Yersinia species (Y. intermedia, Y. kristensenii, and Y. frederiksenii) cultured at 6-8 degrees C were comparatively studied for the first time. The proteins were isolated in two molecular forms (trimeric and monomeric), and their spatial structures were characterized by the methods of optical spectroscopy, CD and intrinsic protein fluorescence. The studied porins were shown to belong to the beta-structural proteins (they have 59-96% total beta structures and 0-17% alpha helices). The spatial structures of the proteins were demonstrated to depend on the nature of the detergent used for solubilization. Unlike the enterobacterial pore-forming proteins, the porin trimers are less stable to sodium dodecyl sulfate (SDS). The spatial structures of the porins become more compact after the substitution of octyl beta-D-glucoside for SDS: the content of beta structures increases and the accessibility of Trp residues to solvent decreases. It was established with the use of the technique of bilayer lipid membranes that the functional properties of the porins are similar to those of the OmpF proteins of Gram-negative bacteria. Trimers are functionally active forms of the porins. Special features of the pore-forming activity of the Yersinia porins were revealed to depend on the microorganism species and the value of the membrane potential.

Abstract
The amino acid sequences of the Yersinia pseudotuberculosis porin (YPS) and Y. pestis porin (YPT) have recently deduced but their three-dimensional structures were not known. These sequences were analyzed using the servers 3D-PSSM and PredPort. The YPS and YPT porins were shown to have a high degree of identity (above 50%) in primary and secondary structures. The three-dimensional models of the Yersinia pseudotuberculosis porin (YPS) and Y. pestis porin (YPT) were obtained using the homology modeling approach, SWISS-MODEL Protein Modeling Server and 3-D structure of PhoE porin from E. coli as template. The superposition of the Calpha-atoms of the monomers of the Yersinia porins and PhoE porin gave a root mean square deviations of 0.47 A and 0.43 A for YPS and YPT respectively. Yersinia porins were found to be very similar in their three-dimensional structure to other non-specific enterobacterial porins, having the same features of overall fold and disposition of loop L3. The intrinsic structures of the monomer pores of YPS and YPT were investigated and their conductances were predicted with the program HOLE. The good correspondence between the theoretical and experimental magnitudes of YPS conductance was found. The Yersinia porins were determined to be unusual in containing the substitution, Glu replaced by Val, in a highly conserved pentapeptide (Pro-Glu-Phe-Gly-Gly-Asp), located in the loop L3 tip that disturbs the functionally important cluster of the acidic amino acids in the constriction site. Comparative analysis of structural organization of YPS and E. coli OmpF porin in the regions involved in subunit association and pore lumen was performed. The YPS porin functional properties were predicted. The differences between these porins in polar interactions playing a significant role in stabilization of the porin trimers were found and discussed in term of the variations in trimer stability. The Yersinia porins were shown to have the highest degree of the structural similarity. The differences between the porins were observed in their external loops. Their loops L6 and loops L8 showed 71.4 and 52.9% of sequence identity, respectively. The arrangement of charged residues clustered in the channel external vestibule of these porins was found to be also different suggesting the possible differences in their functional properties. The surface exposed regions of Yersinia porins involved in their potential sequential antigenic determinants were compared. The structural basis of their cross reactivity and antigenic differences is discussed.

Abstract
Nonspecific pore-forming proteins (porins) are the major proteins of the outer membrane of Gram-negative bacteria responsible for diffusion of low-molecular-weight compounds. Nucleotide sequences of the OmpF-like porins from the pathogenic bacteria Yersinia pseudotuberculosis (YPS) and Yersinia enterocolitica (YE) were cloned and determined. Values of molecular weights (MW) and isoelectric points (IEP) calculated for these proteins (for OmpF-YPS: MW 37.7 kD, IEP 4.45; for OmpF-YE: MW 39.5 kD, IEP 4.34) are in good agreement with experimental data. The OmpF-like Yersinia porins are highly homologous to each other (83-92%) and also to the OmpF protein from Serratia marcescens (70%); the homology to the OmpF porin from E. coli is significantly lower (52-58%). Multiple alignment of the amino acid sequences of mature OmpF proteins provided the distribution of conservative amino acid residues typical for porins. Moreover, the OmpF-like porins from Yersinia are characterized by the presence of extended regions with high and low homologies, which coincide with the transmembrane domains and "external" loops, respectively, of the topological model of the OmpF porin from E. coli. By predictive methods, the secondary structure of the OmpF-like porins from Yersinia was obtained. This structure is represented by 16 beta-strands connected by short "periplasmic" and longer "external" loops with unordered structure.

Abstract
The interaction of Yersinia pseudotuberculosis porin solubilized in deoxycholate with the S- and R-forms of endogenous lipopolysaccharide (LPS) was studied by the quenching of intrinsic protein fluorescence. The samples of S-LPS differed both in the length of O-specific polysaccharide (n = 1 and 4) and in the acylation degree of the 3-hydroxytetradecanoic acid residues of the lipid A moiety (12-66%). R-LPS (12%) binding to porin was found to occur with positive cooperativity on two integrated structural regions of the R-LPS macromolecule, namely, core oligosaccharide and lipid A. The mode of porin interaction with low-acylated S-LPSs (15 or 20%) coincided with a model involving three types of binding sites. The shape of Scatchard curves of binding indicates that a complex formation between porin and low-acylated S-LPS is cooperative at low and moderate ligand concentration, whereas at near-saturating LPS concentrations porin binds to LPS independently on two types of binding sites. The O-specific polysaccharide chain in the S-LPS macromolecule increases the affinity of its interaction with porin in comparison with R-LPS-porin binding. A significant increase (to 66%) in the degree of S-LPS acylation substantially changed its porin-binding character: the process became anti-cooperative with lowered affinity. Thus, the features of LPS-porin interaction significantly depend on the conformational changes in the LPS molecule due to expanding of its hydrophobic region.

Abstract
Certain physicochemical properties of glycoglycerolipids from marine alga Laminaria japonica (monogalactosyl diacylglycerol, digalactosyl diacylglycerol, and sulfoquinovosyl diacylglycerol) and their ability to be incorporated into immunostimulating complexes (ISCOMs) used for presentation of microbial and tumor antigens in vesicular form were comparatively described. These glycolipids proved to considerably differ by fatty acid composition, degree of unsaturation, and phase transition temperature. Possible production of modified ISCOMs through incorporation of these glycolipids into the vesicle instead of the glycolipid component was demonstrated. Preliminary data demonstrated no significant increase in immune response to Yersinia pseudotuberculosis porin within the modified (with monogalactosyl diacylglycerol) and classical (with phosphatidylcholine) ISCOMs as compared to individual porin.

Abstract
Some physicochemical properties of glycoglycerolipids (monogalactosyldiacylglycerol, digalactosyldiacylglycerol and sulfoquinovosyldiacylglycerol) from the sea algae Laminaria japonica, as well as their ability to become incorporate into immunostimulating complexes (ISCOMs), used as a delivery system of microbial and tumor antigens in vesicular form, were studied. These glycolipids were found to differ essentially in fatty acid composition, unsaturation index and thermotropic behavior. The possibility of ISCOM modification by embedding the glycolipids studied instead of a phospholipid component in vesicles was shown. A preliminary research of the immunogenicity of the pore-forming protein from Yersinia pseudotuberculosis in modified (by monogalactosyldiacylglycerol) and typical (egg phosphatidylcholine) ISCOMs did not reveal a significant enhancement of immune response in comparison with that of isolated protein.

Abstract
Changes in the structure and functional activity of porin, a protein from Yersinia pseudotuberculosis, resulting from the removal of lipopolysaccharide (LPS) normally bound with the protein were studied. The treatment of LPS-containing porin with a 30% SDS solution led to an LPS-free protein that, according to the SDS-PAGE, remained to be a trimer. It was shown by CD and UV spectroscopies and intrinsic protein fluorescence that the removal of LPS caused only conformational changes in the porin secondary and tertiary structures. The LPS-free porin folded into a completely beta-structured protein aggregate. The bilayer lipid membrane technique showed that the pore-forming activity of the LPS-free porin decreased, and its concentration should be increased by two orders of magnitude to achieve the same effect. Incubation of the LPS-free porin with LPS led to a porin-LPS complex and affected the character of the protein functional activity. The treatment of the LPS-free porin by octyl glucoside, a nonionic detergent, resulted in the restoration of the protein pore-forming activity. It was suggested that the LPS and detergent provide a definite protein conformation necessary for its functioning.

Abstract
The protective properties of the species-specific pore-forming polypeptide of Y. pseudotuberculosis outer membrane (porin) were studied. The study showed that 80-90% of mice immunized with porin survived after challenge with 10-30 LD50 of Y. pseudotuberculosis, serovars 1 and 3. The LD50 of the preparation exceeded its ED50 more than 100-fold. Immunization made in two injections was more effective than immunization in one injection. The immunization of the animals with porin led to an increase in the activity of peritoneal exudate macrophages with respect to Y. pseudotuberculosis, serovars 1 and 3.

Abstract
The protein moiety of endotoxin from Yersinia pseudotuberculosis was found to consist of two polypeptides with apparent molecular masses 40 and 14.5 kDa (4:1 w/w). The major protein (40 kDa) was isolated from the endotoxin pretreated with sodium deoxy cholate by gel chromatography on the Sephadex G-200 column. Comparative study of this protein and oligomeric form of porin from the outer membrane of Y. pseudotuberculosis using SDS--PAGE, velocity sedimentation, lipid bilayer experiments, chemical and serological analyses revealed their identity. The deoxycholate treatment of the endotoxin does not affect complexes of the major protein and LPS.

Abstract
Using spectroscopic methods (circular dichroism and intrinsic protein fluorescence) and immunoenzyme assay, changes in the spatial and antigenic structure of yersinin, porin from outer membrane of Yersinia pseudotuberculosis, were studied in solutions of ionic and non-ionic detergents at various temperatures and low pH values. Yersinin was shown to retain its secondary structure under various denaturation conditions, the content of regular structural patterns depending on specific action of the denaturation agent. Process of yersinin denaturation similarly to other membrane proteins appears to occur via two structural transitions: dissociation of oligomers and denaturation of monomers. At the first stage changes of quaternary structure accompanied by the loss of so called conformational determinants were observed. Temperature-dependent changes of monomers' tertiary structure affect antigenic activity of yersinin in a smaller degree.

Abstract
The pore-forming protein, lipopolysaccharide-protein complex and lipopolysaccharide of Y. pseudotuberculosis outer membrane have been shown to participate in the penetration of the bacteria into the cells of the macroorganism, to produce a toxic effect on these cells and to enhance the ingesting activity of macrophages in small doses, while suppressing it in large doses. When introduced parenterally, protein induces a more pronounced clinical picture of specific reactive hepatitis in experimental animals and greater changes in their kidneys than the lipopolysaccharide--protein complex.
