The amino acid sequences of nine tryptic peptides (containing altogether 105 amino acids) from human liver glutamic gamma-semialdehyde of dehydrogenase (hitherto designated as ALDH4) were found to correspond, at 33-66% identity, to segments from the yeast 1-proline-5-carboxylate (P5C) dehydrogenase encoded by the PUT2 gene.
