Abstract

A previously uncharacterized Arabidopsis lecithin:cholesterol acyltransferase (LCAT) family gene (At4g19860) was functionally expressed in yeast, where it was demonstrated to encode a novel cytosolic and calcium-independent phospholipase A with preferences for the sn-2 position. This enzyme shows optimal activity at pH 5.0, exhibits a headgroup specificity for phosphatidylcholine>phosphatidic acid>phosphatidylethanolamine>phosphatidylglycerol>phosphatidylserine and has an acyl chain specificity for oleoyl>linoleoyl>ricinoleoyl. The expression of AtLCAT-PLA inhibited yeast cell growth and fatty acid accumulation. AtLCAT-PLA transcript in Arabidopsis was detected at high levels in roots and siliques. Copyright Â
