Abstract

A total of 94 different peptides have been isolated from chymotryptic digests of underivatized (35 mg) and of reduced, carboxymethylated and citraconylated (48 mg) A-protein. Their amino acid sequences provide information for 375 residues of the total of 393 amino acids of the A-protein polypeptide chain. Abnormal specificity of chymotrypsin in the digestion of citraconylated A-protein was observed.
