Regulation of skeletal muscle phosphorylase phosphatase activity. II. Interconversions

Mostrar todas las versiones(3)

1. 1. The incubation of the pegion breast muscle homogenate at 37° resulted in a time-dependent decrease in phosphatase activity. This effect was stimulated by ATP, ADP, AMP, GTP, UTP, CTP or pyrophosphate. 2. 2. Reactivation of an inactive phosphorylase a phosphatase preparation was obtained by inc...
