IntEnz Enzyme Nomenclature


Accepted name:
phospholipase C
Other names:
Clostridium oedematiens β- and γ-toxins
Clostridium welchii α-toxin
heat-labile hemolysin
lecithinase C
lipophosphodiesterase C
lipophosphodiesterase I
phosphatidase C
Systematic name:
phosphatidylcholine cholinephosphohydrolase




The bacterial enzyme, which is a zinc protein, also acts on sphingomyelin and phosphatidylinositol; that from seminal plasma does not act on phosphatidylinositol.
