Lys bond in complement factor B when in complex with complement subcomponent C3b or with cobra venom factor
Reaction: Selective cleavage of ArgLys bond in complement factor B when in complex with complement subcomponent C3b or with cobra venom factor
Other names: C3 proactivator convertase; properdin factor D esterase; factor D; factor D (complement)
Comments: A component of the alternative pathway of complement activation. This reaction is analogous to the activation of complement component C2 by complement subcomponent C
. In peptidase family S1 (trypsin family)
