Comments
Comment typeDescription
Catalytic ActivityPhosphatidylcholine + H(2)O = 1- acylglycerophosphocholine + a carboxylate. {ECO:0000255|PROSITE- ProRule:PRU10035, ECO:0000269|PubMed:14550557}.
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:14550557, ECO:0000269|PubMed:21278126}.
MiscellaneousThe enzyme has a slight preference for phosphatidylethanolamine over phosphatidylcholine.
SimilarityBelongs to the phospholipase A2 family. {ECO:0000305}.
Subcellular LocationSecreted. Golgi apparatus, trans-Golgi network. Endoplasmic reticulum.
Tissue SpecificityStrongly expressed in mature flowers but weakly expressed in other tissues. Detected in buds, open flowers and in pollen. {ECO:0000269|PubMed:14550557, ECO:0000269|PubMed:15748654, ECO:0000269|PubMed:21278126}.
