3.4.21.43 | Selective cleavage of Arg-/-Ser bond in complement component C3 alpha-chain to form C3a and C3b, and Arg-/- bond in complement component C5 alpha-chain to form C5a and C5b |
hydrolyses peptide bond 77 (Arg-Ser) in complement component C3, and complement component C5. Cleavage of C5 requires complement fragment C3b which binds C5 and renders it susceptible to cleavage by the C4b,C2a complex |
