title: [Primary structure of 20S,22R-cholesterol-hydroxylating cytochrome P-450 from bovine adrenal cortex mitochondria. Study of the structure of peptides obtained by hydrolysis of fragment F1 with proteinase from Staphylococcus aureus].
abstract: The fragment F1 resulting from the limited tryptic hydrolysis of the native molecule of cytochrome P-450 has been digested with Staphylococcus aureus protease. 24 peptides, covering the whole polypeptide chain of fragment F1, are isolated from the hydrolysate. Analysis of their amino acid sequence in combination with the earlier data on the structure of cytochrome P-450 chymotryptic peptides and fragment F1 tryptic peptides permitted to carry out a reconstruction of large peptide blocks of fragment F1 that comprise 252 amino acid residues.
