Abstract
Using exclusively high pressure liquid chromatography for the protein and peptide separation complete primary structure of the 12,000 molecular weight (12K) amino terminal (1–87 residues) fragment obtained by mild acid hydrolysis of p27 (Avian Sarcoma Virus structural protein) has been determined. The sequence was established by direct degradation of the native molecule and its (12K) peptides isolated by molecular exclusion and reverse phase HPLC.
