Abstract
We analysed the genetic diversity and environmental correlates of the aldolase A and B genes by means of restriction endonucleases (DNA RFLP analysis), in the four chromosomal species (2n = 52, 54, 58 and 60) of the actively speciating subterranean mole-rats of the Spalax ehrenbergi superspecies in Israel. The results indicated that: (i) both aldolase genes are highly polymorphic; (ii) fragment frequencies and fragment profiles display geographical patterns and significant ecological correlates; (iii) discriminant analysis largely succeeded in separating the four chromosomal species on the basis of variation of aldolase RFLPs.

Abstract
Nucleotide sequence analysis of the Escherichia coli chromosomal DNA inserted in the plasmid pLC33-5 of the Clarke and Carbon library [Clarke & Carbon (1976) Cell 9, 91-99] revealed the existence of the gene, fda, encoding the Class II (metal-dependent) fructose 1,6-bisphosphate aldolase of E. coli. The primary structure of the polypeptide chain inferred from the DNA sequence of the fda gene comprises 359 amino acids, including the initiating methionine residue, from which an Mr of 39,146 could be calculated. This value is in good agreement with that of 40,000 estimated from sodium dodecyl sulphate-polyacrylamide gel electrophoresis of the purified dimeric enzyme. The amino acid sequence of the Class II aldolase from E. coli showed no homology with the known amino acid sequences of Class I (imine-forming) fructose 1,6-bisphosphate aldolases from a wide variety of sources. On the other hand, there was obvious homology with the N-terminal sequence of 40 residues already established for the Class II fructose 1,6-bisphosphate aldolase of Saccharomyces cerevisiae. These Class II aldolases, one from a prokaryote and one from a eukaryote, evidently are structurally and evolutionarily related. A 1029 bp-fragment of DNA incorporating the fda gene was excised from plasmid pLC33-5 by digestion with restriction endonuclease HaeIII and subcloned into the expression plasmid pKK223-3, where the gene came under the control of the tac promoter. When grown in the presence of the inducer isopropyl-beta-D-thiogalactopyranoside, E. coli JM101 cells transformed with this recombinant expression plasmid generated the Class II fructose 1,6-bisphosphate aldolase as approx. 70% of their soluble protein. This unusually high expression of an E. coli gene should greatly facilitate purification of the enzyme for any future structural or mechanistic studies.

Abstract
The amino acid sequence of fructose-1,6-bisphosphate aldolase from Drosophila melanogaster was determined and was compared with those of five vertebrate aldolases on record. The four identical polypeptide chains of the insect enzyme, acetylated at the N-terminus and three residues shorter than the vertebrate chains, contain 360 amino acid residues. Of these 190 (or 53%) are identical in all six enzymes and in addition 33 positions (or 9%) are occupied by homologous residues. Comparison with the muscle-type isoaldolases from man and rabbit and the liver-type isoaldolases from man, rat, and chicken indicates an average sequence identity of 70 and 63%, respectively. Thus, the insect and the vertebrate muscle aldolases are probably coded by orthologous genes. On this basis an average rate of evolution of 3.0 PAM per 10(8) years is calculated, documenting an evolutional divergence slower than that of cytochrome c (4.2 PAM/10(8) years). The rate is also lower than that of the liver isoform (3.6 PAM/10(8) years). Secondary structure prediction analysis for Drosophila aldolase suggests the occurrence of 11-12 helical segments and 8-9 beta-strands. The conspicuous alternation of these structures in all six aldolases, especially in the C-terminal 200 residues, is consistant with the formation of an alpha beta-barrel supersecondary structure as documented for several other glycolytic enzymes.

Abstract
The molecular architecture of the rabbit skeletal muscle aldolase (D-fructose-1,6-bisphosphate D-glyceraldehyde-3-phosphate-lyase, EC 4.1.2.13) tetramer has been determined to 2.7-A resolution. Solution of the three-dimensional structure of rabbit muscle aldolase utilized phase information from a single isomorphous Pt(CN)4(2-) derivative, which was combined with iterative-phase refinement based upon the noncrystallographic 222-fold symmetry exhibited by the tetramer subunits. The electron-density map calculated from the refined phases (mf = 0.72) was interpreted on the basis of the known amino acid sequence (363 amino acids per subunit). The molecular architecture of the aldolase subunit corresponds to a singly wound beta-barrel of the parallel alpha/beta class structures as has been observed in triose phosphate isomerase, pyruvate kinase, phosphogluconate aldolase, as well as others. Close contacts between tetramer subunits are virtually all between regions of hydrophobic residues. Contrary to other beta-barrel structures, the known active-site residues are located in the center of the beta-barrel and are accessible to substrate from the COOH side of the beta-barrel. Biochemical and crystallographic data suggest that the COOH-terminal region of aldolase covers the active-site pocket from the COOH side of the beta-barrel and mediates access to the active site. On the basis of sequence studies, active-site residues as well as residues lining the active-site pocket have been totally conserved throughout evolution. By comparison, homology in the COOH-terminal region is minimal. It is suggested that the amino acid sequence of the COOH-terminal region may be, in part, the basis for the variable specific activities aldolases exhibit toward their substrates.

Abstract
Rabbit liver aldolase B (D-fructose-1,6-bisphosphate D-glyceraldehyde-3-phosphate-lyase, EC 4.1.2.13) contains 8 SH groups/subunit and no disulfide bonds. In the native enzyme 3 SH groups/subunit are titrable with 5,5'-dithiobis(2-nitrobenzoic) acid (Nbs2), 2,2'-dithiodipyridine and N-ethylmaleimide, whereas p-mercuribenzoate is able to react with 4 thiol groups per subunit. Among the three thiol groups titrable with Nbs2, two react 'fast' with simple second-order kinetics, one reacts 'slow' and for this thiol group saturation kinetics is observed, suggesting a reversible binding of Nbs2 to the enzyme prior to covalent modification. It is shown that this binding most likely occurs via ionic interactions in the region close to the active site. The kinetic differentiation between the two 'fast' reacting groups is possible by kinetic analysis of the release of Nbs residues from the modified enzyme. Modification of all exposed SH groups of aldolase B results in 14-32% loss of enzymatic activity. The complete inactivation of liver aldolase by 1 mM p-mercuribenzoate reported previously (Waud, J.M., Feldman, E. and Schray, K.J. (1981) Arch. Biochem. Biophys. 206, 292-295) is shown to be caused by a nonspecific reaction of this reagent used in large excess. It is concluded that this isoenzyme differs from muscle aldolase in the reactivity of exposed SH groups, the mechanisms of the interaction with modifying agents and also in the effect of SH group modification on the enzymatic activity.

Abstract
The structure of the chromosomal gene encoding rat aldolase isozyme B has been elucidated by sequence analysis of cloned genomic DNA. This gene comprises about 14 X 10(3) base-pairs of DNA, and is separated into nine exons by eight intervening sequences. A presumed transcription-initiation site was assigned by S1 nuclease protection mapping, and T-A-T-A and C-C-A-A-T boxes were found to be 25 and 126 base-pairs, respectively, upstream from this initiation site. There are three characteristic sequences of 100 to 200 base-pairs within the region of 870 base-pairs flanking the 5' side of the gene. These sequences are flanked on either side by direct repeats and terminate with an A-rich stretch of nucleotides. One of them has block homology with a region in an "ID sequence", which is reported to be an element for tissue-specific gene regulation and differentiation. The other two are analogous at the sequence organizational level with a sort of dispersed repeat, the "Alu family". These features suggest that these regions are involved in gene regulation and, also, imply evolutionary events such as duplication or insertion. Comparison of this gene sequence with the rabbit aldolase A complementary DNA sequence revealed some bias in the frequency of nucleotide replacement among the exons, suggesting selective evolutionary conservation of particular exons encoding functional domains. Comparison with the human aldolase B complementary DNA sequence revealed no such tendency; the homology between the two sequences was very high (about 89%), and nucleotide replacements were randomly distributed throughout the protein-coding region.

Abstract
The complete amino acid sequence of FBP aldolase from Drosophila melanogaster has been determined. The enzyme contains four identical subunits of 360 amino acid residues. The primary structure of the monomer was established using automated Edman degradation on fragments prepared by CNBr-cleavage, by partial acid cleavage at the unique Asp-Pro bond and by oxidative cleavage at the three tryptophan residues. Manual Edman-Chang degradation was used on smaller peptides obtained by digestion with Staphylococcus aureus V8 protease, trypsin or chymotrypsin. The primary structure of Drosophila aldolase exhibits very extensive homology with the sequence of rabbit muscle aldolase (71% identity), thus explaining the early observation that Drosophila and mammalian aldolases form active interspecies hybrid quaternary structures (Brenner-Holzach, O. and Leuthardt, F., Eur. J. Biochem. (1972) 31, 423-426).

Abstract
Two recombinant clones, pA2 and pA3, containing cDNA sequences for human aldolase B have been isolated from a full length human liver cDNA library. The larger one, pA3, has been subcloned in M13 phage and completely sequenced with the chain terminator method. The sequence covers 1,600 nucleotides including the whole coding region (1,050 nucleotides), 67 nucleotides from the 5' non-coding region and the whole 3' non-coding region, 440 nucleotides long, down to the poly-A tail. Comparison with rabbit aldolase A and with a partial sequence of rat aldolase B, shows a homology of about 76% for aldolase A and of about 94% for aldolase B, which indicates that the sequenced cDNA codes for the liver isoenzyme. This is the first complete sequence reported for human aldolase B. The pA3 clone strongly hybridizes to 18S mRNA from human adult liver as expected from the size of the isolated cDNA.

Abstract
Several aldolase B clones from a human liver cDNA library have been identified by using a rabbit aldolase A cDNA as a hybridization probe. The most complete of these, pHL413, is 1389 base pairs long and covers approximately equal to 80% of the length of the mRNA, including 90% of the translated region. The cDNA, pHL413, was used to identify a genomic clone, lambda HG313, which encoded the remaining amino acids of human aldolase B. We demonstrate that the amino acid and nucleotide sequences of aldolase are strongly conserved even between different isozymes. Furthermore, in the 3'-untranslated regions of the mRNAs for the B isozyme of human and rat there is an extensive stretch of homology. Aldolase B lacks a cysteine at positions 72 and 338 and lacks a histidine at position 361. These residues, which are present in rabbit aldolase A, have previously been proposed to take part in catalysis. Our findings suggest that this may not be the case.

Abstract
Fructose-1,6-bisphosphate aldolase was purified from human skeletal-muscle by affinity elution chromatography. Four CNBr-cleavage fragments were purified by gel filtration, and their N-terminal amino acid sequences were determined. Cleavage with o-iodosobenzoic acid at the three tryptophan residues also yielded fragments suitable for N-terminal sequence analysis. Thus, the sequence of 272 of the 363 residues was established. These sequence results allow many of the discrepancies between the two published rabbit skeletal-muscle aldolase sequences to be resolved. The human aldolase sequence reported here is 96% identical to a "consensus" rabbit aldolase sequence. A comparison with a partial sequence of Drosophila aldolase (103 residues) shows 80% identity. The determination of the amino acid sequence of human aldolase is important for the interpretation of the crystal structure of this enzyme.

Abstract
Ultraviolet difference spectra produced by the binding of mononucleotides and phosphates to rabbit aldolase A and B were analyzed. Both isozymes exhibit a distinct mode of interaction with the ligands. The binding seems to be based on multipoint interaction of nucleotides with each aldolase, indicating the existence of specific nucleotide binding domains in both proteins.
