Abstract
SOME of the enzymes of bovine spleen have been studied in detail and classified as cathepsin A, B and C according to their specificity for certain synthetic peptides1. Examination of the action of rabbit spleen extracts on human serum albumin has shown the existence of a proteolytic activity having an optimal pH at 3.0–3.5 (ref. 2). It was shown that this activity was not due to an enzyme analogous with cathepsin B or C but could have been due to a cathepsin A (ref. 3). Recently we have demonstrated that this activity was due to a single protease which we have purified by chromatography on modified cellulose4.
