Description

1. 1. Both glycerophosphate and monoacylglycerophosphate acyltransferases from Euglena microsomes were inhibited by N-ethylmaleimide, but their responses to heat inactivation and sn-glyceraldehyde-3-phosphate differed. 2. 2. Glycerophosphate acyltransferase had a higher V with palmitoyl-CoA compared to oleoyl-CoA; the reverse was true for monoacylglycerophosphate acyltransferase. 3. 3. Km's (μM) for the glycerophosphate acyltransferase were: palmitoyl-CoA, 21; oleoyl-CoA, 14; and sn-glycerol-3-phosphate, 2900. Km's (μM) for monoacylglycerophosphate acyltransferase were: palmitoyl-CoA, 7; oleoyl-CoA, 4; and 1-palmitoyl-sn-glycerol-3-phosphate, 48.
