Protein
Phospholipase A1-Ialpha2, chloroplastic
Organism
Arabidopsis thaliana
Function
Acylhydrolase that catalyzes the hydrolysis of phosphatidylcholine at the sn-1 position. Has a strong galactolipase activity toward monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG). Low triacylglycerol (TAG) lipase activity. Plays a role in plant growth and in leaf senescence.
Similarity
Belongs to the AB hydrolase superfamily. Lipase family.
