| Enzyme Function | 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. {ECO:0000269|PubMed:17259290}. |
