Enzyme Information
| 3.4.21.41 |
Complement subcomponent C1r.
based on mapping to UniProt P00736
Selective cleavage of Lys(or Arg)-|-Ile bond in complement subcomponent C1s to form the active form of C1s (EC 3.4.21.42).
-!- Activates C1s by proteolytic cleavage so that it can, in turn, activate C2 and C4. -!- Activated from proenzyme C1r in plasma by autocatalytic mechanism during activation of the complement system by the 'classical' route. -!- Belongs to peptidase family S1.
