The covalent structure of calf skin type III collagen. VI. The amino acid sequence of the carboxyterminal cyanogen bromide peptide alpha 1(III)CB9B (position 928--1028).

The C-terminal cyanogen bromide peptide alpha 1(III)CB9B is 101 amino acid residues in length and occupies position 928--1028 along the alpha 1(III) chain. For sequence analysis, alpha 1(III)CB9B was fragmented with trypsin and chymotrypsin. The peptides obtained were separated using molecular sieve and ion exchange chromatography and sequenced using the automated Edman degradation procedure.
