title: The amino acid sequence of chick skin collagen alpha1-CB7.
abstract: The amino acid sequence of chick skin collagen alpha1-CB7, the 268 CNBr peptide from the helical portion of the alpha1 chain, has been determined by automatic and manual degradation of tryptic and chymotryptic peptides, and of the COOH-terminal fragment produced by cleavage with animal collagenase. The resulting sequence shows 94% identity with that of the corresponding peptide from calf skin collage (Fietzek, P. P., Rexrodt, F. W., Hopper, K. E., and Kühn, K. (1973), Eur. J. Biochem. 38, 396). The bond cleaved by animal collagenase has been identified as Gly-Ile at residues 221-222 of alpha1-CB7.
