3-O-alpha-D-glucosyl-L-rhamnose phosphorylase (EC 2.4.1.282, cphy1019 (gene)) is an enzyme with systematic name 3-O-alpha-D-glucopyranosyl-L-rhamnopyranose:phosphate beta-D-glucosyltransferase. [1] This enzyme catalyses the following chemical reaction

3-O-alpha-D-glucopyranosyl-L-rhamnopyranose + phosphate L-rhamnopyranose + beta-D-glucose 1-phosphate

In the reverse phosphorolysis reaction the enzyme is specific for L-rhamnose as acceptor and beta-D-glucose 1-phosphate as donor.

<span class="mw-page-title-main">Glycogen phosphorylase</span> Class of enzymes

Glycogen phosphorylase is one of the phosphorylase enzymes. Glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis in animals by releasing glucose-1-phosphate from the terminal alpha-1,4-glycosidic bond. Glycogen phosphorylase is also studied as a model protein regulated by both reversible phosphorylation and allosteric effects.

<span class="mw-page-title-main">Myophosphorylase</span> Muscle enzyme involved in glycogen breakdown

Myophosphorylase or glycogen phosphorylase, muscle associated (PYGM) is the muscle isoform of the enzyme glycogen phosphorylase and is encoded by the PYGM gene. This enzyme helps break down glycogen into glucose-1-phosphate, so it can be used within the muscle cell. Mutations in this gene are associated with McArdle disease, a glycogen storage disease of muscle.

<span class="mw-page-title-main">Sucrose phosphorylase</span>

Sucrose phosphorylase is an important enzyme in the metabolism of sucrose and regulation of other metabolic intermediates. Sucrose phosphorylase is in the class of hexosyltransferases. More specifically it has been placed in the retaining glycoside hydrolases family although it catalyzes a transglycosidation rather than hydrolysis. Sucrose phosphorylase catalyzes the conversion of sucrose to D-fructose and α-D-glucose-1-phosphate. It has been shown in multiple experiments that the enzyme catalyzes this conversion by a double displacement mechanism.
