Comments
Comment typeDescription
Biophysicochemical PropertiespH dependence: Optimum pH is 6.0-6.5. {ECO:0000269|PubMed:11595796};
Catalytic ActivityPhosphatidylcholine + H(2)O = 2- acylglycerophosphocholine + a carboxylate. {ECO:0000269|PubMed:11595796, ECO:0000269|PubMed:19527719}.
Disruption PhenotypeDefective in anther dehiscence and pollen maturation. Delayed flower buds opening. {ECO:0000269|PubMed:11595796}.
FunctionSn-1-specific phospholipase that releases free fatty acids from phospholipids. Low activity on galactolipids and triacylglycerols. Catalyzes the initial step of jasmonic acid biosynthesis. Not essential for jasmonate biosynthesis after wounding or upon pathogen infection. {ECO:0000269|PubMed:11595796, ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:20348210}.
InductionBy wounding. {ECO:0000269|PubMed:11595796, ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:20348210}.
MiscellaneousDirectly regulated at the transcription level by the floral homeotic gene AGAMOUS.
Sequence CautionSequence=AAC31843.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305}; Sequence=AAL69449.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305}; Sequence=AAM14879.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305}; Sequence=AEC10469.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
SimilarityBelongs to the AB hydrolase superfamily. Lipase family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast {ECO:0000269|PubMed:11595796, ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:19527719}.
Tissue SpecificityExpressed in flower buds, but not in leaves or roots. Restricted to the stamen filaments immediately before flower opening. {ECO:0000269|PubMed:11595796, ECO:0000269|PubMed:18267087, ECO:0000269|PubMed:19527719}.
