Abstract:

Two heat-stable inhibitors (a and b) of phosphoprotein phosphatases I and II from Mucor rouxii were isolated from mycelium of the fungus. They were partially purified from extracts by heating, DEAE-cellulose chromatography, and Sephadex G-75 gel filtration. The molecular weights of inhibitors a and b, estimated by gel filtration, are 5,000 and 20,000 respectively. Inhibitor a acts similarly on both enzymes while inhibitor b is relatively more active on enzyme II. Storage of inhibitor b at -20 °C for several weeks resulted in a partial conversion to a lower-molecular-weight form with properties similar to those of inhibitor a. © 1985.
