in dystrophic muscle , the specific and total activities of serine protease were much higher than in normal muscle , and the specific activities , but not the total activities , of cathepsin b1 and ornithine aminotransferase were twice those in normal muscle , and several new fragments , which are normally formed by limited proteolysis , were found in dystrophic muscle .
