Structure of C3f, a small peptide specifically released during inactivation of the third component of complement.
C3f, a peptide presumed to be generated by the combined actions of factors I and H on fluid-phase C3b, has been isolated and sequenced. The peptide is 17 residues long and has a molecular weight of 1,847 daltons. The amino-terminal sequence is, with the exception of a single residue, identical to that deduced for the 46-kilodalton polypeptide seen transiently in the generation of iC3b from C3b, and is in full agreement with the sequence deduced from cDNA analysis. In addition, high-pressure liquid chromatography of the digestion of C3b by factor I has shown that C3f is the sole peptide released during iC3b generation.
