摘要: A disulfide-bonded peptide with a molecular weight of about 100 000 was isolated from the medium cultured chick embryo tendons. It shown to be trimer two types subunits in 2:1 ratio, and tryptic fingerprinting immunological evidence indicated that it derived carboxy-terminal-precursor-specific region procollagen. Amino acid analysis after reduction alkylation contains 30 residues half-cystine involved intrachain as well interchain disulfide bonding. The bonds could reduced alkylated under nondenaturing conditions. Carbohydrate showed each three chains N-acetylglucosamine ten mannose. This suggests presence one or oligosaccharide units per chain.
