Glucan phosphorylase [Carbohydrate transport and metabolism].

proteins similar to glycogen phosphorylase. This family is most closely related to the oligosaccharide phosphorylase domain family and other unidentified sequences. Oligosaccharide phosphorylase catalyzes the breakdown of oligosaccharides into glucose-1-phosphate units. They are important allosteric enzymes in carbohydrate metabolism.

alpha-glucan phosphorylases. This family consists of known phosphorylases, and homologs believed to share the function of using inorganic phosphate to cleave an alpha 1,4 linkage between the terminal glucose residue and the rest of the polymer (maltodextrin, glycogen, etc.). The name of the glucose storage polymer substrate, and therefore the name of this enzyme, depends on the chain lengths and branching patterns. A number of the members of this family have been shown to operate on small maltodextrins, as may be obtained by utilization of exogenous sources. This family represents a distinct clade from the related family modeled by TIGR02093/pfam00343.

glycogen synthase GSY2 and similar proteins. Glycogen synthase, which is most closely related to the GT3 family of glycosyltransferases, catalyzes the transfer of a glucose molecule from UDP-glucose to a terminal branch of a glycogen molecule, a rate-limit step of glycogen biosynthesis. GSY2, the member of this family in S. cerevisiae, has been shown to possess glycogen synthase activity.

Glycogen synthase. This family consists of the eukaryotic glycogen synthase proteins GYS1, GYS2 and GYS3. Glycogen synthase (GS) is the enzyme responsible for the synthesis of -1,4-linked glucose chains in glycogen. It is the rate limiting enzyme in the synthesis of the polysaccharide, and its activity is highly regulated through phosphorylation at multiple sites and also by allosteric effectors, mainly glucose 6-phosphate (G6P).
