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. |
