Abstract

Bacteriorhodopsin in dimyristoylphosphatidylcholine vesicles is randomly distributed in the plane of the membrane and exhibits rotational diffusion above the gel to liquid-crystalline phase transition. Incorporation of cholesterol results in loss of rotational mobility of bacteriorhodopsin, which on the basis of electron microscopy and CD measurements can be assigned to the formation of protein aggregates. It is concluded that bacteriorhodopsin is soluble in the fluid phosphatidylcholine phase but segregates when cholesterol is present in the lipid bilayer.
