Clostridiopeptidase B (EC 3.4.22.8) was not inhibited by stoichiometric amounts of lima bean trypsin inhibitor, ovomucoid trypsin inhibitor, Kuntiz bovine trypsin inhibotor, Kunitz soybean trypsin inhibitor or ovoinhibitor. Activity was diminished at relatively high concentrations of the three latter inhibitors. Human plasma alpha 2-macroglobulin inhibited both the amidase and protease activity of the enzyme. Rat and dog plasmas contained high molecular weight inhibitors, presumably macroglobulins as well. Inhibition by this component was greater in rat plasma than in dog plasma, which may be related to the observation that clostridiopeptidase B-induced generation of kinin activity is indirect in the former plasma, but direct in the later. Leupeptin (N-acetyl-L-leucyl-L-leucyl-L-argininal) and antipain ([S)-1-carboxy-2-phenylethyl] carbamoyl-L-arginyl-L-valyl-L-argininal) inhibited clostridiopeptidase B (Ki of 2 . 10(-8) and 3 . 10(-8) M, respectively). They were potent inhibitors of clostridiopeptidase B-induced kinin release in dog plasma.
