  • Title: Primary structure of streptococcal proteinase. II. Isolation, composition, and amino acid sequences of the tryptic and chymotryptic peptides of cyanogen bromide fragment 5.
    Author: Tai JY, Liu TY.
    Journal: J Biol Chem; 1976 Apr 10; 251(7):1948-54. PubMed ID: 1270416.
    Abstract:
    The amino acid sequence of the cyanogen bromide fragment 5 of streptococcal proteinase has been determined. This fragment comprises residues 130 to 253 of the proteinase chain. Six tryptic peptides were isolated from maleylated cyanogen bromide fragment 5, and their alignment was obtained by the overlap of chymotryptic peptides. Sequence analysis of tryptic, chymotryptic, and thermolysin peptides was performed by the 5-deimethylaminoaphthalene-1-sulfonyl technique and carboxypeptidases digestion.
