N2 - A cDNA clone, named ppcMDH-1 and covering a part of the coding region for the porcine cytosolic malate dehydrogenase (cMDH) mRNA, was isolated from a porcine liver cDNA library. Subsequently, mouse cMDH cDNA clones were isolated from mouse liver and heart cDNA libraries, using the ppcMDH-1 cDNA as a probe. The longest clone, named pmcMDH-5, was sequenced and the primary structure of the mouse cMDH deduced from its cDNA sequence showed that the mouse cMDH consists of the 334-amino acid residues. When the amino acid sequence of the mouse cMDH was compared with that of the porcine cMDH, they shared a 93% homology. On the other hand, the amino acid sequences of mouse cMDH and mitochondrial MDH (mMDH) showed about 23% overall homology. Surprisingly, comparison of the amino acid sequences among the mammalian and bacterial MDHs revealed that the homology between the mouse cMDH and thermophilic bacterial MDH, as well as the homology between the mouse mMDH and Escherichia coli MDH, markedly exceeds the intraspecies sequence homology between mMDH and cMDH from mice.
