Papain inhibitor
Based on 1 Customer Validation
Papain inhibitor (Glycylglycyl-L-tyrosyl-L-arginine) is a competitive papain-targeting enzyme inhibitor with a Ki of 9 μM. Papain inhibitor binds directly to the substrate binding site of papain, inhibiting substrate hydrolysis by the enzyme. Papain inhibitor functions as a component of an electrochemical probe for the detection of papain.

Biological Activity
Papain[1].
Papain inhibitor (Compound 7) acts as a competitive inhibitor of purified papain with an inhibition constant of 9 μM at pH 6.2[1].
Papain inhibitor binds to purified papain at pH 6.2, inducing a 30 mV cathodic shift in its ferrocene/ferrocenium redox potential[1].
