Comment typeDescription
Biophysicochemical PropertiespH dependence: Optimum pH is 7.0. {ECO:0000269|PubMed:18267087};
Catalytic Activity1,2-diacyl-3-beta-D-galactosyl-sn-glycerol + 2 H(2)O = 3-beta-D-galactosyl-sn-glycerol + 2 carboxylates. {ECO:0000269|PubMed:19527719}.
Catalytic ActivityPhosphatidylcholine + H(2)O = 2- acylglycerophosphocholine + a carboxylate. {ECO:0000269|PubMed:19527719}.
Disruption PhenotypeNo visible phenotype under standard growth phenotype. {ECO:0000269|PubMed:20348210}.
FunctionSn-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. {ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:20348210}.
InductionBy wounding. {ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:20348210}.
MiscellaneousOverexpression of DGL causes a dwarf phenotype.
SimilarityBelongs to the AB hydrolase superfamily. Lipase family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast {ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:19527719, ECO:0000269|PubMed:20348210}. Note=PubMed:20348210 shows a localization in lipid droplets.
Tissue SpecificityExpressed in leaves and seedlings. Not detected in flowers, siliques or roots. {ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:19527719}.
