cysteine proteinase inhibitors isolated from rat and human epidermis were purified to homogeneity and had isoelectric points of ph 4.31 and ph 5.10 , respectively , both inhibitors caused noncompetitive inhibition to the same degree against papain ( ec 3.4.22.2 ) , but the activity of human inhibitor against rat liver cathepsins b ( ec 3.4.22.1 ) , h ( ec 3.4.22.16 ) , and l ( ec 3.422.- ) was more effective than that of rat inhibitor .
