Catalyzes the release of fatty acids from lysophospholipids. 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 (By similarity). a 1-acyl-sn-glycero-3-phosphocholine + H2O = a fatty acid + H(+) + sn-glycerol 3-phosphocholine Belongs to the lysophospholipase family.
