A more basic protein than Cathepsin B or L. Functions as both an aminopeptidase and endopeptidase. Cathepsin H, like cathepsin L and B, is involved in the catabolism of proteins in the lysosomal system. Activity: greater than 1 unit per mg protein. One unit is defined as the amount of enzyme that hydrolyzes one umole of L-arginine-beta-napthylamide per minute at 40oC using 75 mM potasium phosphate, pH 6.8, with 1 mM EDTA and 3 mM cysteine as the activation buffer. Prepared from tissue shown to be non reactive for HbsAG, anti-HCV, anti-HBc, and negative for anti-HIV 1 2 by FDA approved tests. >95percent pure by SDS-PAGE.
