these findings , taken with the observation that phosphorylase phosphatase , beta-phosphorylase kinase phosphatase , glycogen synthase phosphatase-1 and glycogen synthase phosphatase-2 activities co-purified up to the sephadex g-200 step , suggest that a single protein phosphatase ( protein phosphatase-iii ) catalyses each of the dephosphorylation reactions that inhibit glycogenolysis or stimulate glycogen synthesis .
