Cytochrome P450IIB1 isolated from rat liver microsomes was incorporated into phosphatidylcholine/phosphatidylethanolamine/phosphatidylserine (10:5:1 w/w) liposomes. Trypsinolysis of proteoliposomes and sequencing of the membrane-bound domains revealed that only one peptide, comprising amino acid residues 1-21, spans the membrane. Modification of the N-terminal methionine by membrane-impermeable fluorescein isothiocyanate occurred with the protein in solution but not in proteoliposomes. We conclude that in proteoliposomes cytochrome P-450 spans the membrane only with amino acid residues 1-21, the N-terminal methionine facing the lumen.
