Abstract
Compositional analysis of the soluble tryptic peptides representing about 70% of the 293 residues of sn-glycerol-3-phosphate dehydrogenase in Drosophila melanogaster reveals a single peptide difference between the sn-glycerol-3-phosphate dehydrogenase adult (GPDHF-1) and larval (GPDHF-3) isozymes. This peptide was shown to be the carboxyl terminus by sequence determination and by carboxypeptidase A digestion of the native protein. For GPDHF-1, the sequence of the COOH-terminal tryptic peptide is Asn-His-Pro-Glu-His-Met-Gln-Asn-Leu-COOH, while that of GPDHF-3 is Asn-His-Pro-Glu-His-Met-COOH.
