alpha-N-benzoylarginine-2-naphthylamide hydrolase (cathepsin B1 ?) from rat skin. II. Purification of the enzyme and demonstration of two inhibitors in the skin.


A thiol-activated, alpha-N-benzoylarginine-2-naph-thylamide (BANA) hydrolyzing enzyme was purified from rat skin by ammonium sulfate precipitation, gel filtration, and DEAE cellulose chromatography. In DEAE cellulose chromatography the enzyme was fractionated into two multiple forms (preparations I and II). The activity of undiluted preparation II, but not… (More)
