Abstract

We examined the effect of surface pressure on the interfacial binding and phospholipase A2 activity of lecithin-cholesterol acyltransferase. The enzyme bound to phosphatidylcholine monolayers with an apparent dissociation constant of 1.5 nM was excluded from the interface at pressures > 29 mN/m and exhibited maximal phospholipase activity at pressures between 26-28 mN/m. These data suggest that lipoprotein surface pressure may regulate lecithin-cholesterol acyltransferase activity in vivo.
