Chain A   (PHLC_CLOP1 | Q0TV31)
molecular function
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0016788    hydrolase activity, acting on ester bonds    Catalysis of the hydrolysis of any ester bond.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0034480    phosphatidylcholine phospholipase C activity    Catalysis of the reaction: phosphatidylcholine + H2O = 1,2-diacylglycerol + a choline phosphate.
    GO:0004629    phospholipase C activity    Catalysis of the reaction: a phospholipid + H2O = 1,2-diacylglycerol + a phosphatidate.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0019835    cytolysis    The rupture of cell membranes and the loss of cytoplasm.
    GO:0044179    hemolysis in other organism    The cytolytic destruction of red blood cells, with the release of intracellular hemoglobin, in one organism by another.
    GO:0009405    pathogenesis    The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.
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.
