AB  - The complement-enhancing property of bovine carboxypeptidase A is lost when the enzyme is treated with acetylimidazole. Bovine carboxypeptidase B is as effective in enhancing guinea pig complement as carboxypeptidase A when used at five times the molar concentration as the latter. These data suggest that the peptidase, and not the esterase, activity of carboxypeptidase A is associated with the complement-enhancing property. Bovine procarboxypeptidase A, inert in immune hemolysis, will, when treated with trypsin, enhance guinea pig complement.
