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.

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.

Glucan phosphorylase [Carbohydrate transport and metabolism].

Carbohydrate phosphorylase. The members of this family catalyze the formation of glucose 1-phosphate from one of the following polyglucoses; glycogen, starch, glucan or maltodextrin.

Glycogen synthase [Carbohydrate transport and metabolism].
