Three overlapping cDNA clones encoding methylmalonate-semialdehyde dehydrogenase (MMSDH; 2-methyl-3-oxopropanoate:NAD+ oxidoreductase (CoA-propanoylating); EC 1.2.1.27) have been isolated by screening a rat liver lambda gt 11 library with nondegenerate oligonucleotide probes synthesized according to polymerase chain reaction-amplified portions coding for the N-terminal amino acid sequence of rat liver MMSDH. The three clones cover a total of 1942 base pairs of cDNA, with an open reading frame of 1569 base pairs. The authenticity of the composite cDNA was confirmed by a perfect match of 43 amino acids known from protein sequencing. The composite cDNA predicts a 503 amino acid mature protein with M(r) = 55,330, consistent with previous estimates. Polymerase chain reaction was used to obtain the sequence of the 32 amino acids corresponding to the mitochondrial entry peptide. Northern blot analysis of total RNA from several rat tissues showed a single mRNA band of 3.8 kilobases. Relative mRNA levels were: kidney greater than liver greater than heart greater than muscle greater than brain, which differed somewhat from relative MMSDH protein levels determined by Western blot analysis: liver = kidney greater than heart greater than muscle greater than brain. A 1423-base pair cDNA clone encoding human MMSDH was isolated from a human liver lambda gt 11 library. The human MMSDH cDNA contains an open reading frame of 1293 base pairs that encodes the protein from Leu-74 to the C terminus. Human and rat MMSDH share 89.6 and 97.7% identity in nucleotide and protein sequence, respectively. MMSDH clearly belongs to a superfamily of aldehyde dehydrogenases and is closely related to betaine aldehyde dehydrogenase, 2-hydroxymuconic semialdehyde dehydrogenase, and class 1 and 2 aldehyde dehydrogenases.
