Abstract
The N-terminal amino acid sequences of dogfish pepsinogen (8 residues), seal pepsinogen (26 residues) and bovine pepsinogen B (25 residues) have been determined. The primary structures of all three pepsinogens show considerable homology with those of zymogens of gastric proteases sequenced previously.
