Comments
Comment typeDescription
Catalytic ActivityPhosphatidylcholine + H(2)O = 1- acylglycerophosphocholine + a carboxylate. {ECO:0000255|PROSITE- ProRule:PRU10035}.
CofactorName=Ca(2+); Xref=ChEBI:CHEBI:29108; Note=Binds 1 Ca(2+) ion per subunit.;
Developmental StageExpressed during pollen germination and tube growth. {ECO:0000269|PubMed:21278126}.
FunctionPA2 catalyzes the calcium-dependent hydrolysis of the 2- acyl groups in 3-sn-phosphoglycerides. Releases lysophospholipids (LPLs) and free fatty acids (FFAs) from membrane phospholipids in response to hormones and other external stimuli. Plays a role in pollen development and germination and tube growth. {ECO:0000269|PubMed:21278126}.
MiscellaneousThe enzyme has a slight preference for phosphatidylethanolamine over phosphatidylcholine.
Sequence CautionSequence=CAB79705.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
SimilarityBelongs to the phospholipase A2 family. {ECO:0000305}.
Subcellular LocationSecreted {ECO:0000250}. Endoplasmic reticulum {ECO:0000269|PubMed:21278126}.
Tissue SpecificitySpecifically expressed in flowers but at a low level. Detected specifically in the pollen. {ECO:0000269|PubMed:15748654, ECO:0000269|PubMed:21278126}.
