The present studies clearly document the smaller fragment, C2b, that results when human C2 reacts with C1s. We have identified and characterized C2b (34,000 daltons) as a single protein on disc electrophoresis and immunoelectrophoresis. C2a (73,000 daltons), the larger fragment from this reaction, has a more acidic nature and C2b is more basic. These fragments can also be detected by their different antigenic determinants. When the C2-C4b complex is activated in the fluid phase by C1s and allowed to decay, it dissociates into C2a and the C2b-C4b complex. Furthermore, when C2 is bound to C4b-Sepharose and then reacted with C1s, only the C2a fragment is released from the solid phase C2-C4b-Sepharose into the fluid phase, and the C2b fragment remains noncovalently bound to C4b-Sepharose. These results suggest that the C2b portion of C2 contains a stable binding site for C4b and, after the decay release of C2a from this C3 convertase, the C2b fragment remains bound. Thus, the decay release of C2a may represent a temperature-dependent dissociation from C2b."xsd:string |
