Abstract
The effect of nonlamellar-prone lipids, diacylglycerol (DG) and phosphatidylethanolamine (PE), on the ATPase activity of SecA was examined. When Escherichia coli (E. coli) PE of the standard vesicles composed of 60 mol％ of this lipid and 40 mol％ of dioleoylphosphatidylglycerol (DOPG) is gradually replaced with either dioleoylgylcerol (DOG) or dioeloyl PE(DOPE), the ATPase activity of SecA present together increased appreciably.(omitted)
