Protein
Phospholipase A1-IIdelta
Organism
Arabidopsis thaliana
Function
Acylhydrolase that catalyzes the hydrolysis of phosphatidylcholine (PC) at the sn-1 position. High activity toward PC, medium activity toward monogalactosyldiacylglycerol (MGDG) and low activity toward triacylglycerol (TAG). Confers sensitivity to UV-B radiation probably by deesterifying membrane phospholipids.
Similarity
Belongs to the AB hydrolase superfamily. Lipase family.
