II. Inactivation of Aldolase by Membrane-Bound Lysosomal Proteinases... [Pg.77]

During the course of our earlier studies on the conversion of fructose 1,6-bisphosphatase (Fru-Pgase) from the neutral to the alkaline form by lysosomal proteinases from rabbit liver (14-16) we observed that a considerable fraction of the converting enzyme activity, designated CE-II (15), remained associated with the insoluble membrane fraction after disruption of the lysosomes by freezing and thawing. This membrane-bound activity was found to be almost fully expressed by undisrupted rabbit liver lysosomes (15, 17). Rabbit liver cathepsin B, which also exhibited Fru-Paase-converting enzyme activity (15, 17, 18), was not present in the membrane fraction and was not responsible for the activity observed with intact lysosomes (17). [Pg.78]
