Protein
Galactolipase DONGLE, chloroplastic
Organism
Arabidopsis thaliana
Function
Sn-1-specific phospholipase that releases free fatty acids from phosphatidylcholine. Has a higher galactolipase activity than phospholipase A1 activity when digalactosyldiacylglycerol (DGDG) is used as substrate. Catalyzes the initial step of jasmonic acid biosynthesis. Required for the biosynthesis of basal-level endogenous jasmonate in vegetative tissues. Regulates leaves growth. Not essential for jasmonate biosynthesis after wounding or upon pathogen infection.
Similarity
Belongs to the AB hydrolase superfamily. Lipase family.
