Lipid metabolism in microsomal fraction from photosynthetic tissue. Effects of catalase and hydrogen peroxide on oleate desaturation.

Abstract

On incubation of microsomal fraction from pea (Pisum sativum L.) leaves with ammonium [1-14C]oleate or [1-14C]oleoyl-CoA in the presence of ATP, CoA, Mg2+ and NADH, the major reactions observed were those catalysed by oleoyl-CoA synthetase, oleoyl-CoA thioesterase, oleoyl-CoA:phosphatidylcholine acyltransferase and oleoyl phosphatidylcholine desaturase. The reaction catalysed by oleoyl phosphatidylcholine desaturase was specifically inhibited by H2O2, and this inhibitory effect was overcome by catalase (EC 1.11.1.6).
