[Cytochrome P-450 in proteoliposomes: oligomeric structure of the LM2 isoform]

Crosslinking of protein molecules with bifunctional reagents and subsequent electrophoresis of the modified proteins revealed the presence of cytochrome P-450 LM 2 oligomers in proteoliposome membranes obtained in different ways and differing in their phospholipid composition. Data from a comparative analysis of cytochrome P-450 oligomeric structures in solution and in membrane are suggestive of the hexameric organization of cytochrome P-450 LM 2 within proteoliposome membranes.
