Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (PA2H1_BOTPI | P58399)
molecular function
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0004623    phospholipase A2 activity    Catalysis of the reaction: phosphatidylcholine + H2O = 1-acylglycerophosphocholine + a carboxylate.
biological process
    GO:0016042    lipid catabolic process    The chemical reactions and pathways resulting in the breakdown of lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
