Catalyzes the release of fatty acids from lysophospholipids (By similarity). Phospholipase B may well contribute to pathogenicity by abetting the fungus in damaging and traversing host cell membranes, processes which likely increase the rapidity of disseminated infection (PubMed:9748287). a 1-acyl-sn-glycero-3-phosphocholine + H2O = a fatty acid + H(+) + sn-glycerol 3-phosphocholine Expressed during candidal infection of mice. Reduces dramatically the ability to penetrate host cells. Belongs to the lysophospholipase family.
