Mammalian glycogen synthase, with its complex multisite phosphorylation mechanisms, continues to provide interesting and novel examples of the regulation of protein function. The mammalian enzyme is phosphorylated in a hierarchal manner such that modification of certain sites requires the prior phosphorylation of other sites. Yeast contains two glycogen synthases that have extensive similarities to their mammalian counterpart but the greatest divergence in amino acid sequence is seen precisely in the regions likely to be involved in covalent control. We hope that examination of the control of the yeast glycogen synthase will be as informative as study of the mammalian enzymes, whether by revealing important parallels with the mammalian system or by uncovering major differences in mechanism.
