Myoglobin from Atlantic and Tinker mackerels: Purification, characterization and its possible use as a molecular marker. Int J Biol Macromol 2022; 214:459-469. [PMID: 35753513 DOI: 10.1016/j.ijbiomac.2022.06.128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 06/13/2022] [Accepted: 06/18/2022] [Indexed: 11/20/2022]
Abstract
Here, we report the characterization (purification, autoxidation rate, pseudoperoxidase activity) and amino acid sequence determination of S. scombrus (Atlantic mackerel) and S. colias (Tinker mackerel) mioglobins (Mbs), considering the increasing consumption of fresh and canned mackerel meat and Mb implication in meat storage (e.g.: browning and lipid oxidation). We found that Atlantic mackerel Mb has major autoxidation rate (0.204 ± 0.013 h-1) compared to Tinker mackerel Mb (0.140 ± 0.009 h-1), while the pseudoperoxidase activity is major for Tinker mackerel (Km: 87.71 ± 7.19 μM; kcat: 0.32 s-1) Mb with respect to Atlantic mackerel (Km: 96.08 ± 6.91 μM; kcat: 0.50 s-1). These functional differences are confirmed by primary structure determination, in which six amino acid substitutions are found, with the first N-terminal amino acid residue acetylated. Furthermore, we predicted by AphaFold 3D model both fish Mbs and used them to investigate the possible structural differences. In addition, phylogenetic analysis using Mb sequences from Scombridae family confirms that Atlantic and Tinker mackerels are two distinct species. Finally, an analytic qualitative RP-HPLC method to distinguish S. scombrus and S. colias specimens was developed considering the different retention times of the two mackerel apoMbs.

Ca 2+ as activator of pseudoperoxidase activity of pigeon, Eurasian woodcock and chicken myoglobins: New features for meat preservation studies. Food Chem 2021; 363:130234. [PMID: 34126569 DOI: 10.1016/j.foodchem.2021.130234] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 05/24/2021] [Accepted: 05/26/2021] [Indexed: 11/25/2022]
Abstract
Myoglobin (Mb), hemeprotein that binds dioxygen in muscle, affects meat colour. Moreover, in presence of peroxides, metMb is a potent oxidant involved in oxidative rancidity in meat. Here, following pigeon Mb purification and primary structure mass spectroscopy characterization, we determined its autoxidation rate and pseudoperoxidase activity with respect to chicken and E. woodcock Mbs. The three Mbs exhibit different autoxidation rates (0.153-h-1 pigeon, 0.194-h-1 chicken and 0.220-h-1 E. woodcock Mbs) and similar specificity constant (9.86x103 M-1s-1 pigeon, 8.81x103 M-1s-1 chicken and 9.90x103 M-1s-1 E. woodcock Mbs), considering their pseudoperoxidase activity. Moreover, for the first time, we detected an increase in pseudoperoxidase activity in presence of Ca2+, particularly at pH 5.8. NMR and CD data indicate that the nonspecific Ca2+ binding induces small local structural rearrangements that in turn slightly reduce pigeon Mb thermal stability. However, considering Ca2+ concentration variations before and post-mortem, this finding must be considered for meat preservation.

Abstract
The adsorption of proteins from aqueous medium leads to the formation of protein corona on nanoparticles. The formation of protein corona is governed by a complex interplay of protein-particle and protein-protein interactions, such as electrostatics, van der Waals, hydrophobic, hydrogen bonding, and solvation. The experimental parameters influencing these interactions, and thus governing the protein corona formation on nanoparticles, are currently poorly understood. This lack of understanding is due to the complexity in the surface charge distribution and anisotropic shape of the protein molecules. Here, we investigate the effect of pH and salinity on the characteristics of corona formed by myoglobin on silica nanoparticles. We experimentally measure and theoretically model the adsorption isotherms of myoglobin binding to silica nanoparticles. By combining adsorption studies with surface electrostatic mapping of myoglobin, we demonstrate that a monolayered hard corona is formed in low salinity dispersions, which transforms into a multilayered hard + soft corona upon the addition of salt. We attribute the observed changes in protein adsorption behavior with increasing pH and salinity to the change in electrostatic interactions and surface charge regulation effects. This study provides insights into the mechanism of protein adsorption and corona formation on nanoparticles, which would guide future studies on optimizing nanoparticle design for maximum functional benefits and minimum toxicity.

Transglutaminase-mediated crosslinking of a host defence peptide derived from human apolipoprotein B and its effect on the peptide antimicrobial activity. Biochim Biophys Acta Gen Subj 2020; 1865:129803. [PMID: 33249170 DOI: 10.1016/j.bbagen.2020.129803] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 11/03/2020] [Accepted: 11/23/2020] [Indexed: 01/14/2023]
Abstract
Background Microbial transglutaminase (mTG) has been successfully used to produce site-specific protein conjugates derivatized at the level of Gln and/or Lys residues for different biotechnological applications. Here, a recombinant peptide identified in human apolipoprotein B sequence, named r(P)ApoBL and endowed with antimicrobial activity, was studied as a possible acyl acceptor substrate of mTG with at least one of the six Lys residues present in its sequence. Methods The enzymatic crosslinking reaction was performed in vitro using N,N-dimethylcasein, substance P and bitter vetch (Vicia ervilia) seed proteins, well known acyl donor substrates in mTG-catalyzed reactions. Mass spectrometry analyses were performed for identifying the Lys residue(s) involved in the crosslinking reaction. Finally, bitter vetch protein-based antimicrobial films grafted with r(P)ApoBL were prepared and, their biological activity evaluated. Results r(P)ApoBL was able to be enzymatically modified by mTG. In particular, it was demonstrated the highly selective crosslinking of the peptide under study by mTG at level of Lys-18. Interestingly, the biological activity of the peptide when grafted into protein-based films was found to be lost following mTG-catalyzed crosslinking. Conclusions r(P)ApoBL was shown to be an effective acyl acceptor substrate of mTG. The involvement of Lys-18 in the enzymatic reaction was demonstrated. In addition, films grafted with r(P)ApoBL in the presence of mTG lost antimicrobial property. General significance A possible role of mTG as biotechnological tool to modulate the r(P)ApoBL antimicrobial activity was hypothesized, and a potential use in food packaging of protein-based films grafted with r(P)ApoBL was suggested.

Abstract
An immunochromatographic detection of myoglobin (MG) as a specific marker of porcine muscle tissue has been developed. The method is based on the sandwich lateral flow immunoassay (LFIA) with gold nanoparticles (AuNPs) as a label. The developed test system determines MG with a detection limit of 5 ng mL−1 within 15 min. A specific determination of porcine MG and no cross-reactivity with MG from other tested mammals and bird species was demonstrated. The test system is able to detect pork additives, as low as 0.01% (w/w), in minced beef. A technique of MG extraction from muscle tissue has been proposed which allows for rapid and efficient MG extraction from meat samples (within 20 min). The developed test system can serve as an effective means of controlling the authenticity and quality of meat products.

Gene Organization, Expression, and Localization of Ribotoxin-Like Protein Ageritin in Fruiting Body and Mycelium of Agrocybe aegerita. Int J Mol Sci 2020; 21:ijms21197158.

Abstract
The edible mushroom Agrocybe aegerita produces a ribotoxin-like protein known as Ageritin. In this work, the gene encoding Ageritin was characterized by sequence analysis. It contains several typical features of fungal genes such as three short introns (60, 55 and 69 bp) located at the 5' region of the coding sequence and typical splice junctions. This sequence codes for a precursor of 156 amino acids (~17-kDa) containing an additional N-terminal peptide of 21 amino acid residues, absent in the purified toxin (135 amino acid residues; ~15-kDa). The presence of 17-kDa and 15-kDa forms was investigated by Western blot in specific parts of fruiting body and in mycelia of A. aegerita. Data show that the 15-kDa Ageritin is the only form retrieved in the fruiting body and the principal form in mycelium. The immunolocalization by confocal laser scanning microscopy and transmission electron microscopy proves that Ageritin has vacuolar localization in hyphae. Coupling these data with a bioinformatics approach, we suggest that the N-terminal peptide of Ageritin (not found in the purified toxin) is a new signal peptide in fungi involved in intracellular routing from endoplasmic reticulum to vacuole, necessary for self-defense of A. aegerita ribosomes from Ageritin toxicity.
