Change in the alpha-glucosidase activity of cattle muscle tissue during slow autolysis]

Changes in the alpha-glucosidase activity of the cattle muscular tissue (oxen eye muscle of loin) were evaluated during storage at 2 degrees. Under these conditions both lysosomal and extralysosomal alpha-glucosidase activities underwent no significant changes during a long period of time (12 days). Activity of lysosome-bound alpha-glucosidase was about 10% of total enzyme activity in the homogenate; the remaining part of alpha-glucosidase was contained outside lysosomes.
