Abstract
Malate dehydrogenase (MDH) is a ubiquitous enzyme involved in cellular respiration across all domains of life. MDH's ubiquity allows it to act as an excellent model for considering the history of life and how the rise of aerobic respiration and eukaryogenesis influenced this evolutionary process. Here, we present the diversity of the MDH family of enzymes across bacteria, archaea, and eukarya, the relationship between MDH and lactate dehydrogenase (LDH) in the formation of a protein superfamily, and the connections between MDH and endosymbiosis in the formation of mitochondria and chloroplasts. The development of novel and powerful DNA sequencing techniques has challenged some of the conventional wisdom underlying MDH evolution and suggests a history dominated by gene duplication, horizontal gene transfer, and cryptic endosymbiosis events and adaptation to a diverse range of environments across all domains of life over evolutionary time. The data also suggest a superfamily of proteins that do not share high levels of sequential similarity but yet retain strong conservation of core function via key amino acid residues and secondary structural components. As DNA sequencing and 'big data' analysis techniques continue to improve in the life sciences, it is likely that the story of MDH will continue to refine as more examples of superfamily diversity are recovered from nature and analyzed.

Abstract
A photoelectrochemical biosensor for malate was developed using an indium tin oxide (ITO) layer deposited on a poly(ethylene terephthalate) plastic sheet as a transparent electrode material for the immobilization of malate dehydrogenase together with CdTe quantum dots. Different approaches were compared for the construction of the bioactive layer; the highest response was achieved by depositing malate dehydrogenase together with CdTe nanoparticles and covering it with a Nafion/water (1:1) mixture. The amperometric signal of this biosensor was recorded during irradiation with a near-UV LED in the flow-through mode. The limit of detection was 0.28 mmol/L, which is adequate for analyzing malic acid levels in drinks such as white wines and fruit juices. The results confirm that the cheap ITO layer deposited on the plastic sheet after cutting into rectangular electrodes allows for the economic production of photoelectrochemical (bio)sensors. The combination of NAD+-dependent malate dehydrogenase with quantum dots was also compatible with such an ITO surface.

Abstract
Malate valves act as powerful systems for balancing the ATP/NAD(P)H ratio required in various subcellular compartments in plant cells. As components of malate valves, isoforms of malate dehydrogenases (MDHs) and dicarboxylate translocators catalyse the reversible interconversion of malate and oxaloacetate and their transport. Depending on the co-enzyme specificity of the MDH isoforms, either NADH or NADPH can be transported indirectly. Arabidopsis thaliana possesses nine genes encoding MDH isoenzymes. Activities of NAD-dependent MDHs have been detected in mitochondria, peroxisomes, cytosol and plastids. In addition, chloroplasts possess a NADP-dependent MDH isoform. The NADP-MDH as part of the 'light malate valve' plays an important role as a poising mechanism to adjust the ATP/NADPH ratio in the stroma. Its activity is strictly regulated by post-translational redox-modification mediated via the ferredoxin-thioredoxin system and fine control via the NADP+ /NADP(H) ratio, thereby maintaining redox homeostasis under changing conditions. In contrast, the plastid NAD-MDH ('dark malate valve') is constitutively active and its lack leads to failure in early embryo development. While redox regulation of the main cytosolic MDH isoform has been shown, knowledge about regulation of the other two cytosolic MDHs as well as NAD-MDH isoforms from peroxisomes and mitochondria is still lacking. Knockout mutants lacking the isoforms from chloroplasts, mitochondria and peroxisomes have been characterised, but not much is known about cytosolic NAD-MDH isoforms and their role in planta. This review updates the current knowledge on MDH isoforms and the shuttle systems for intercompartmental dicarboxylate exchange, focusing on the various metabolic functions of these valves.

Abstract
Malate dehydrogenase (MDH) is an enzyme widely distributed among living organisms and is a key protein in the central oxidative pathway. It catalyzes the interconversion between malate and oxaloacetate using NAD+ or NADP+ as a cofactor. Surprisingly, this enzyme has been extensively studied in eukaryotes but there are few reports about this enzyme in prokaryotes. It is necessary to review the relevant information to gain a better understanding of the function of this enzyme. Our review of the data generated from studies in bacteria shows much diversity in their molecular properties, including weight, oligomeric states, cofactor and substrate binding affinities, as well as differences in the direction of the enzymatic reaction. Furthermore, due to the importance of its function, the transcription and activity of this enzyme are rigorously regulated. Crystal structures of MDH from different bacterial sources led to the identification of the regions involved in substrate and cofactor binding and the residues important for the dimer-dimer interface. This structural information allows one to make direct modifications to improve the enzyme catalysis by increasing its activity, cofactor binding capacity, substrate specificity, and thermostability. A comparative analysis of the phylogenetic reconstruction of MDH reveals interesting facts about its evolutionary history, dividing this superfamily of proteins into two principle clades and establishing relationships between MDHs from different cellular compartments from archaea, bacteria, and eukaryotes.

Abstract
The tricarboxylic acid (TCA) cycle plays two essential roles in metabolism. First, under aerobic conditions the cycle is responsible for the total oxidation of acetyl-CoA that is derived mainly from the pyruvate produced by glycolysis. Second, TCA cycle intermediates are required in the biosynthesis of several amino acids. Although the TCA cycle has long been considered a "housekeeping" pathway in Escherichia coli and Salmonella enterica, the pathway is highly regulated at the transcriptional level. Much of this control is exerted in response to respiratory conditions. The TCA cycle gene-protein relationship and mutant phenotypes have been well studied, although a few loose ends remain. The realization that a "shadow" TCA cycle exists that proceeds through methylcitrate has cleared up prior ambiguities. The glyoxylate bypass has long been known to be essential for growth on carbon sources such as acetate or fatty acids because this pathway allowsnet conversion of acetyl-CoA to metabolic intermediates. Strains lacking this pathway fail to grow on these carbon sources, since acetate carbon entering the TCA cycle is quantitatively lost as CO2 resulting in the lack of a means to replenish the dicarboxylic acids consumed in amino acid biosynthesis. The TCA cycle gene-protein relationship and mutant phenotypes have been well studied, although the identity of the small molecule ligand that modulates transcriptional control of the glyoxylate cycle genes by binding to the IclR repressor remains unknown. The activity of the cycle is also exerted at the enzyme level by the reversible phosphorylation of the TCA cycle enzyme isocitrate dehydrogenase catalyzed by a specific kinase/phosphatase to allow isocitratelyase to compete for isocitrate and cleave this intermediate to glyoxylate and succinate.

Abstract
A novel malate dehydrogenase (MDH; EC 3.1.1.1.37), hereafter MDHCs, from Ceratonia siliqua seeds, commonly known as Carob tree, was purified by using ammonium sulphate precipitation, ion exchange chromatography on SteamLine SP and gel-filtration. The molecular mass of the native protein, obtained by analytical gel-filtration, was about 65 kDa, whereas, by using SDS-PAGE analysis, with and without reducing agent, was 34 kDa. The specific activity of purified MDHCs (0.25 mg/100 g seeds) was estimated to be 188 U/mg. The optimum activity of the enzyme is at pH 8.5, showing a decrease in the presence of Ca(2+), Mg(2+) and NaCl. The N-terminal sequence of the first 20 amino acids of MDHCs revealed 95 % identity with malate dehydrogenase from Medicago sativa L. Finally, the enzymatic activity of MDHCs was preserved even after absorption onto a PVDF membrane. To our knowledge, this is the first contribution to the characterization of an enzyme from Carob tree sources.

Abstract
The genes of the mitochondrial and cytosolic malate dehydrogenase (mMDH and cMDH) of Phytophthora infestans were cloned and overexpressed in Escherichia coli as active enzymes. The catalytic properties of these proteins were determined: both enzymes have a similar specific activity. In addition, the natural mitochondrial isoenzyme was semi-purified from mycelia and its catalytic properties determined: the recombinant mitochondrial isoform behaved as the natural enzyme. A phylogenetic analysis indicated that mMDH, present in all stramenopiles studied, can be useful to study the relationships between these organisms. MDH with the conserved domain MDH_cytoplasmic_cytosolic is absent in some stramenopiles as well as in fungi. This enzyme seems to be less related within the stramenopile group. The Phytophthora cMDHs have an insertion of six amino acids that is also present in the stramenopile cMDHs studied, with the exception of Thalassiosira pseudonana cMDH, and is absent in other known eukaryotic cMDHs.

Abstract
The cytosol and mitochondrial malate dehydrogenases (MDHs, EC 1.1.1.37) of Clonorchis sinensis were expressed in Escherichia coli as a fusion protein with a 6xHis and GST tag, respectively. The cytosol MDH of Clonorchis sinensis (Cs-cMDH) has higher resistibility to acid than mitochondrial MDH (Cs-mMDH). The Cs-cMDH also has higher heat resistibility and thermal stability than Cs-mMDH. Although there is only 22.8% identity between the amino acid sequences of Cs-cMDH and Cs-mMDH, they share several conserved residues. There are some differences between the circular dichroism spectra of Cs-cMDH and Cs-mMDH, but they have approximate percentages of helix. 4,4'-Bisdimethylamino diphenylcarbinol can decrease the Cs-mMDH activity but not the Cs-cMDH activity. Paraziquantel, metronidazole and albendazole did not inhibit the enzymes' activity, but adenosine 5'-monophosphate showed competitive inhibition to enzyme, with the Ki for Cs-cMDH and Cs-mMDH being 2.81 and 0.49 mM, respectively.

Abstract
We have cloned and sequenced a lactate dehydrogenase (LDH) gene from Cryptosporidium parvum (CpLDH1). With this addition, and that of four recently deposited alpha-proteobacterial malate dehydrogenase (MDH) genes, the phylogenetic relationships among apicomplexan LDH and bacterial MDH were re-examined. Consistent with previous studies, our maximum likelihood (ML) analysis using the quartet-puzzling method divided 105 LDH/MDH enzymes into five clades, and confirmed that mitochondrial MDH is a sister clade to those of y-proteobacteria, rather than to alpha-proteobacteria. In addition, a Cryptosporidium parvum MDH (CpMDH1) was identified from the ongoing Cryptosporidium genome project that appears to belong to a distinct clade (III) comprised of 22 sequences from one archaebacterium, numerous eubacteria, and several apicomplexans. Using the ML puzzling test and bootstrapping analysis with protein distance and parsimony methods, the resulting trees not only robustly confirmed the alpha-proteobacterial relationship of apicomplexan LDH/MDH, but also supported a monophyletic relationship of CpLDH1 with CpMDHI. These data suggest that, unlike most other eukaryotes, the Apicomplexa may be one of the few lineages retaining an alpha-proteobacterial-type MDH that could have been acquired from an ancestral alpha-proteobacterium through primary endosymbiosis giving rise to the mitochondria, or through an unknown lateral gene transfer (LGT) event.

Abstract
The aromatic l-alpha-hydroxy acid dehydrogenase (AHDAH) from Trypanosoma cruzi has over 50% sequence identity with cytosolic malate dehydrogenases (cMDHs), yet it is unable to reduce oxaloacetate. Molecular modeling of the three-dimensional structure of AHADH using the pig cMDH as template directed the construction of several mutants. AHADH shares with MDHs the essential catalytic residues H195 and R171 (using Eventoff's numbering). The AHADH A102R mutant became able to reduce oxaloacetate, while remaining fully active towards aromatic alpha-oxoacids. The Y237G mutant diminished its affinity for all of the natural substrates, whereas the double mutant A102R/Y237G was more active than Y237G and had similar activity with oxaloacetate and with aromatic substrates. The present results reinforce our proposal that AHADH arose by a moderate number of point mutations from a cMDH no longer present in the parasite.

Abstract
The evolutionary history of the malate dehydrogenase (MDH) gene family [NAD-dependent MDH; EC 1.1.1.37 and NAD(P)-dependent MDH; EC 1.1.1.82] has received much attention. MDHs have also featured extensively as electrophoretic markers in population genetics and evolutionary ecology, and in many cases, intraspecific variation in MDH has been correlated with environmental variables. However, while the amino acid residues essential for MDH function are known, no studies have examined intraspecific nucleotide variation despite evidence indicating that natural selection may be operating on this locus. This study presents two sets of degenerate oligonucleotide PCR primers to facilitate the cloning of cytosolic MDH (cMDH) and mitochondrial MDH (mMDH) from a broad range of animals (cMDH) and animals and plants (mMDH). These primers were used to obtain putative cMDH and mMDH cDNAs from the mollusc Nucella lapillus. The N. lapillus cMDH cDNA was found to encode a putative cMDH protein of 334aa and 36kDa, while the mMDH cDNA encoded a putative mature mMDH protein of 315aa and 33kDa. The putative amino acid sequences of the two compartmentalised N. lapillus MDHs are presented and compared to other known MDH sequences.

Abstract
Lactate dehydrogenase (LDH) is present in the amitochondriate parasitic protist Trichomonas vaginalis and some but not all other trichomonad species. The derived amino acid sequence of T. vaginalis LDH (TvLDH) was found to be more closely related to the cytosolic malate dehydrogenase (MDH) of the same species than to any other LDH. A key difference between the two T. vaginalis sequences was that Arg91 of MDH, known to be important in coordinating the C-4 carboxyl of oxalacetate/malate, was replaced by Leu91 in LDH. The change Leu91Arg by site-directed mutagenesis converted TvLDH into an MDH. The reverse single amino acid change Arg91Leu in TvMDH, however, gave a product with no measurable LDH activity. Phylogenetic reconstructions indicate that TvLDH arose from an MDH relatively recently.

Abstract
We report a novel plastidic NAD-dependent malate dehydrogenase (EC 1. 1.1.37), which is not redox-regulated in contrast to its NADP-specific counterpart (EC 1.1.1.82). Analysis of isoenzyme patterns revealed a single NAD-MDH associated with highly purified chloroplasts isolated from Arabidopsis and spinach. A cDNA clone encoding the novel enzyme was found in the Arabidopsis EST data base by sorting all putative clones for NAD-dependent malate dehydrogenase. A derived amino acid sequence is very similar to mitochondrial and peroxisomal NAD-MDHs within the region coding for the mature protein but possesses a 80-amino acid long N-terminal domain with typical characteristics of a chloroplast transit peptide. In vitro synthesized labeled precursor protein was imported into the stroma of spinach chloroplasts and processed to a mature enzyme subunit of 34 kDa. Expressed in Escherichia coli, the recombinant enzyme exhibited the same distinctive isoelectric point of 5.35 as the original enzyme from Arabidopsis chloroplasts. Northern analysis revealed that the protein is expressed in both autotrophic and heterotrophic tissues. The findings reported here indicate that the "malate valve" operates not only in the illuminated chloroplasts but also in dark chloroplasts and in heterotrophic plastids and is therefore a general mechanism to maintain the optimal ratio between ATP and reducing equivalents in plastids.

Abstract
Here we report the first complete sequence of plant cytosolic malate dehydrogenase (EC 1.1.1.37). The phylogenetic relationships between malate dehydrogenases from different cell compartments are discussed. The constructed phylogenetic tree shows that cytosolic NAD-MDH and chloroplast NADP-MDH have evolved through gene duplication of the pre-existing nuclear gene.

Abstract
The N-terminal sequences of malate dehydrogenases from 10 bacterial strains, representing seven genera of Proteobacteria, were determined. Of these, the enzyme sequences of species classified in the genus Brevundimonas clearly resembled those malate dehydrogenases with greatest similarity to lactate dehydrogenases. Additional evidence from subunit molecular weights, peptide mapping, and enzyme mobilities suggested that malate dehydrogenases from species of the genus Brevundimonas were structurally distinct from others in the study.

Abstract
The gene encoding malate dehydrogenase (mdhA) was obtained from the psychrophilic, barophilic, deep-sea isolate Photobacterium species strain SS9. The SS9 mdhA gene directed high levels of malate dehydrogenase (MDH) production in Escherichia coli. A comparison of SS9 MDH to three mesophile MDHs, a MDH sequence obtained from another deep-sea bacterium, and to other psychrophile proteins is presented.

Abstract
Malate dehydrogenase from the syntrophic propionate-oxidizing bacterium strain MPOB was purified 42-fold. The native enzyme had an apparent molecular mass of 68 kDa and consisted of two subunits of 35 kDa. The enzyme exhibited maximum activity with oxaloacetate at pH 8.5 and 60 degrees C. The Ka for oxaloacetate was 50 microM and for NADH 30 microM. The Km values for L-malate and NAD were 4 and 1.1 mM, respectively. Substrate inhibition was found at oxaloacetate concentrations higher than 250 microM. The N-terminal amino acid sequence of the enzyme was similar to the sequences of a variety of other malate dehydrogenases from plants, animals and micro-organisms.

Abstract
The gene encoding the tetrameric malate dehydrogenase (MDH) in a thermophilic Bacillus species (BI) has been cloned in an Escherichia coli plasmid. The nucleotide sequence of the gene, the first to be elucidated for a tetrameric MDH, shows the MDH subunit to contain 312 amino acids and have a molecular mass of 33648 Da, which confirms the experimentally determined value of about 35 kDa. Like the genomic DNA of BI, the MDH gene is relatively AT-rich; this contrasts with the generally GC-rich nature of the DNA of thermophilic Bacillus species. Comparison of amino acid sequences reveals that BI MDH bears greater structural similarity to lactate dehydrogenases (LDHs) than to other (dimeric) MDHs. MDHs and LDHs resemble each other in catalytic mechanism and several other respects. However, whereas MDHs in the majority of organisms are dimers, the tetrameric structure is favoured among LDHs. The stronger structural resemblance that BI MDH has to LDHs than to the dimeric MDHs provides some explanation as to why Bacillus MDH, unlike most other MDHs, is tetrameric. A 1 kb fragment containing the BI MDH gene, produced in a PCR, has been cloned into a high-expression E. coli plasmid vector. BI MDH synthesized from this clone constitutes about 47% of the total protein in cell extracts of the E. coli strain carrying the clone. MDH purified from BI and that purified from the E. coli strain carrying the MDH gene clone appear to be identical proteins by several criteria. A number of characteristics of the MDH have been elucidated, including the molecular masses of the native enzyme and the subunit, N-terminal amino acid sequence, isoelectric point, pH optimum for activity, thermostability, stability to pH, urea and guanidinium chloride and several kinetic parameters. Whereas the MDH is a stable tetramer in the pH range 5-7, it appears to be converted into a stable dimer at pH 3.5. This suggests that the dimer is a stable intermediate in the dissociation of the tetramer to monomers at low pH.

Abstract
The nucleotide sequence of a gene coding for a 37 kDa subunit of a cytosolic malate dehydrogenase of Trichomonas vaginalis was established. The sequence of a gDNA clone and a cDNA clone, which lacked seven amino-terminal codons, were identical, indicating an absence of introns from the gene. Cell fractionation combined with sequencing of peptide fragments of the purified enzyme showed that the gene codes for an expressed cytosolic enzyme. The derived amino acid sequence was closely related to cytosolic malate dehydrogenases from animals and plants and from the eubacteria Thermus aquaticus and Mycobacterium leprae and was more distant from the enzyme of mitochondria and from Escherichia coli and certain other eubacteria. In phylogenetic reconstructions this enzyme shared a most recent common ancestor with other cytosolic enzymes.

Abstract
Malate dehydrogenases are widely distributed and alignment of the amino acid sequences show that the enzyme has diverged into 2 main phylogenetic groups. Multiple amino acid sequence alignments of malate dehydrogenases also show that there is a low degree of primary structural similarity, apart from in several positions crucial for nucleotide binding, catalysis, and the subunit interface. The 3-dimensional structures of several malate dehydrogenases are similar, despite their low amino acid sequence identity. The coenzyme specificity of malate dehydrogenase may be modulated by substitution of a single residue, as can the substrate specificity. The mechanism of catalysis of malate dehydrogenase is similar to that of lactate dehydrogenase, an enzyme with which it shares a similar 3-dimensional structure. Substitution of a single amino acid residue of a lactate dehydrogenase changes the enzyme specificity to that of a malate dehydrogenase, but a similar substitution in a malate dehydrogenase resulted in relaxation of the high degree of specificity for oxaloacetate. Knowledge of the 3-dimensional structures of malate and lactate dehydrogenases allows the redesign of enzymes by rational rather than random mutation and may have important commercial implications.

Abstract
The nucleotide (nt) sequence of mdh (encoding malate dehydrogenase) in Salmonella typhimurium is presented. The relative positions of argR (encoding arginine repressor) and mdh on the chromosome of S. typhimurium were determined from analysis of the nt sequence. The homology of the 3'-terminal end with only one of two published mdh sequences in Escherichia coli identifies the correct sequence in this organism.

Abstract
Malate dehydrogenases belong to the most active enzymes in glyoxysomes, mitochondria, peroxisomes, chloroplasts and the cytosol. In this review, the properties and the role of the isoenzymes in different compartments of the cell are compared, with emphasis on molecular biological aspects. Structure and function of malate dehydrogenase isoenzymes from plants, mammalian cells and ascomycetes (yeast, Neurospora) are considered. Significant information on evolutionary aspects and characterisation of functional domains of the enzymes emanates from bacterial malate and lactate dehydrogenases modified by protein engineering. The review endeavours to give up-to-date information on the biogenesis and intracellular targeting of malate dehydrogenase isoenzymes as well as enzymes cooperating with them in the flow of metabolites of a given pathway and organelle.

Abstract
Purified pea chloroplast NADP-malate dehydrogenase (S)-malate: NADP+ oxidoreductase, EC 1.1.1.82) was digested with trypsin and the resulting peptides were separated by HPLC and sequenced. Together with the information from earlier work (Fickenscher, K. et al. (1987) Eur. J. Biochem. 168, 653-658) the total sequence is not known to an extent of 78%. Comparison with the sequence of the corn NADP-malate dehydrogenase deduced from its cDNA (Metzler, M.C. et al. (1989) Plant Mol. Biol. 12, 713-722) showed 84% agreement; however, the 11 N-terminal residues exhibit only 27% similarity. The N- and C-terminal extrapeptides of the pea NADP-malate dehydrogenase when aligned with non-regulatory NAD-malate dehydrogenases from bacteria or mammals consist of 30 and 17 amino acids, respectively. Since all cysteine-containing peptides were sequenced, the number of eight cysteines per subunit of the pea enzyme was established. The native, oxidized enzyme is characterized by an extremely slow reactivity of two thiols. Titration of the thiols of the denatured, oxidized enzyme both with DTNB and with pCMB resulted in six thiols not involved in disulfide formation. Therefore, one disulfide bridge must be present per 38.9 kDa subunit. Analysis of disulfide bonds by urea gel electrophoresis confirmed this finding. Using digestion products of NADP-malate dehydrogenase with aminopeptidase K, the location of the single disulfide bridge was established to be on the N-terminal arm (Cys-12 and Cys-17) of the polypeptide chain.

Abstract
Both the mouse cytosolic malate dehydrogenase gene and its mitochondrial counterpart contain eight introns, of which two are present at identical positions between the isozyme genes. The probability that the two intron positions coincide by chance between the two genes has been shown to be significantly small (= 1.3 x 10(-3), suggesting that the conservation of the intron positions has a biological significance. On the basis of a rooted phylogenetic tree inferred from a comparison of these isozymes and lactate dehydrogenases, we have shown that the origins of the conserved introns are very old, possibly going back to a date before the divergence of eubacteria, archaebacteria, and eukaryotes. In the aspartate aminotransferase isozyme genes, five of the introns are at identical places. The origins of the five conserved introns, however, are not obvious at present. It remains possible that some or all of the conserved introns have evolved after the divergence of eubacteria and eukaryotes.

Abstract
The alignments of the amino acid sequences of inorganic pyrophosphatase (PPase) from Saccharomyces cerevisiae (Y1-PPase, 286 amino acids) and Escherichia coli (E-PPase, 175 amino acids) are examined in the light of crystallographic and chemical modification results placing specific amino acid residues at the active site of the yeast enzyme. The major results are: (1) the full E-PPase sequence aligns within residues 28-225 of Y1-PPase, raising the possibility that the N-terminal and C-terminal portions of Y1-PPase may not be essential for activity, and (2) that whereas the overall identity between the two sequences is only modest (22-27% depending on the choice of alignment parameters), of some 17 putative active site residues, 14-16 are identical between Y-PPase and E-PPase. PPase thus appears to be an example of enzymes from widely divergent species that conserve common functional elements within the context of substantial overall sequence variation.

Abstract
L-Malate dehydrogenase from the extremely thermophilic mathanogen Methanothermus fervidus was isolated and its phenotypic properties were characterized. The primary structure of the protein was deducted from the coding gene. The enzyme is a homomeric dimer with a molecular mass of 70 kDa, possesses low specificity for NAD+ or NADP+ and catalyzes preferentially the reduction of oxalacetate. The temperature dependence of the activity as depicted in the Arrhenius and van't Hoff plots shows discontinuities near 52 degrees C, as was found for glyceraldehyde-3-phosphate dehydrogenase from the same organism. With respect to the primary structure, the archaebacterial L-malate dehydrogenase deviates strikingly from the eubacterial and eukaryotic enzymes. The sequence similarity is even lower than that between the L-malate dehydrogenases and L-lactate dehydrogenases of eubacteria and eukaryotes. The phylogenetic meaning of this relationship is discussed.

Abstract
42 residues of the N-terminal amino acid sequence of malate dehydrogenase from the thermoacidophilic archaebacterium Sulfolobus acidocaldarius have been determined as VKVAFIGVGRGVGQTIAYNTIVNGYADEVMLYDVVPELPTKK. In eubacterial and eukaryotic enzymes this region is known to encompass residues involved in pyridine nucleotide binding. In the archaebacterial enzyme the residues Gly-7, Gly-11 and Asp-33 are also present. The data suggest that in the enzyme from S. acidocaldarius like in the other malate dehydrogenases the binding domain for NAD(H) is localized at the N-terminal part of the polypeptide chain. The archaebacterial enzyme is homologous to the other malate dehydrogenases, of which the amino acid sequences are known, however, it is only distantly related to the mitochondrial/E. coli group and the cytosolic/Thermus flavus group.

Abstract
Small patches of identical amino acid sequences commonly occur in proteins that have the same function but are derived from evolutionarily distant organisms. Reverse translation of such patches into degenerate pools of oligonucleotides provide useful hybridization probes for cloning the gene for the corresponding protein from other organisms. Since the conserved patches of identical amino acid sequence are probably important for the protein's biological function, they are preferred targets for reverse genetic studies aimed at defining structure-function relationships.
