EC 3.1.4.3 Details
EC number
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
CAS registry number
9001-86-9
Comment
The bacterial enzyme, which is a zinc protein, also acts on sphingomyelin and phosphatidylinositol; that from seminal plasma does not act on phosphatidylinositol.
