Alpha 2 high molecular mass cysteine proteinase inhibitor: HMr alpha 2-CPI. An inhibitor of human liver cathepsin H as probed by kinetic study.

HMr alpha 2CPI was found to be an inhibitor of human liver cathepsin H by the measurement of the dissociation constant (Ki), the association rate constant (k1) and the dissociation rate constant (k-1) between the enzyme and the inhibitor. These data suggest that this protein-proteinase inhibitor can play a physiological role in the regulation of free cathepsin H.
