the role of insulin in the regulation of the key rate-limiting enzymes of glycogen synthesis ( glycogen synthase ) and glycogen breakdown ( glycogen phosphorylase ) was studied as was the role of the key phosphoprotein phosphatase enzymes that regulate activation of synthase ( synthase phosphatase ) and inactivation of phosphorylase ( phosphorylase phosphatase ) .
