Enzymes not used in glycogen metabolism

The liver phosphorylase-b is the inactive form. It becomes active on phosphorylation. The active form is phosphorylase-a.Glycogen synthase exists in two distinct forms that can be interconveed by the action of specific enzymes; active dephosphorylated glycogen synthase(glucose-6-p-independent) and less active, phosphorylated glycogen synthase D(glucose-6-p-dependent.Ref: DM Vasudevan, page no: 127
