Sea anemone phospholipase A2 (PLA2) that may have a role both in defense and in digestion, since its expression and enzymatic activity were found both in the acontia (defensive organs) and tentacles. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) Binds 1 Ca(2+) ion per subunit. Belongs to the phospholipase A2 family.
