title: Amino acid sequence of chitinase from Streptomyces erythraeus.
abstract: The amino acid sequence of chitinase from Streptomyces erythraeus was determined by the conventional method. The amino acid sequences of tryptic peptides of the reduced and S-carboxymethylated protein were determined. The tryptic peptides were aligned by overlapping the amino acid sequences of chymotryptic peptides, lysyl endopeptidase peptides and cyanogen bromide fragments. S. erythraeus chitinase consists of 290 amino acid residues with the molecular weight of 30,400 and has two disulfide bridges at Cys(45)-Cys(89) and Cys(265)-Cys(272). The enzyme has no significant homology with other chitinases, lysozymes, and other proteins.
