Important role in the infectious process. May contribute to efficient lysis of the two-membrane vacuoles that surround the bacteria after direct cell-to-cell spread. a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1,2-diacyl-sn-glycerol + H(+) + phosphocholine Binds 3 Zn(2+) ions per subunit. Belongs to the bacterial zinc-metallophospholipase C family.
