title: Investigation of peptides containing half-cystine in pig pancreas amylase.
abstract: Sequence analysis of the carboxymethyl-cystein-containing tryptic peptides isolated after the total reduction and carboxymethylation of pig pancreas amylase has shown that the half-cystine-containing tryptic peptides of the isozymes have identical sequences. The fact that 10 tryptic peptides containing carboxymethyl-cystein could be isolated, supports the generally accepted view that pig pancreas amylase contains single polypeptide chain.
