Abstract
Polypeptides are disclosed which inhibit the binding of the C5a chemotaxin to polymorphonuclear leukocytes by cleaving a six amino acid peptide from the carboxy-terminus of the C5a chemotaxin. The polypeptides can be isolated from virulent strains of group A streptococci, s. pyogenes, by enzymatic or detergent extraction.
