EC 3.1.4.3     
Accepted name: phospholipase C
Reaction: a phosphatidylcholine + H2O = 1,2-diacyl-sn-glycerol + phosphocholine
Other name(s): lipophosphodiesterase I; lecithinase C; Clostridium welchii α-toxin; Clostridium oedematiens β- and γ-toxins; lipophosphodiesterase C; phosphatidase C; heat-labile hemolysin; α-toxin
Systematic name: phosphatidylcholine cholinephosphohydrolase
Comments: The bacterial enzyme, which is a zinc protein, also acts on sphingomyelin and phosphatidylinositol; that from seminal plasma does not act on phosphatidylinositol.
