Starch Phosphorylase (Phosphorylase, Starch)

An enzyme of the PHOSPHORYLASES family that catalyzes the degradation of starch, a mixture of unbranched AMYLOSE and branched AMYLOPECTIN compounds. This phosphorylase from plants is the counterpart of GLYCOGEN PHOSPHORYLASE in animals that catalyzes the reaction of inorganic phosphate on the terminal alpha-1,4-glycosidic bond at the non-reducing end of glucans resulting in the release of glucose-1-phosphate.

Also Known As:

Phosphorylase, Starch; Amylophosphorylase; Starch Phosphorylase a; Starch Phosphorylase b; Phosphorylase a, Starch; Phosphorylase b, Starch

2.	Weight Loss (Weight Reduction) 11/01/2022 - "The citral-loaded hollow MIL-88A induced a sustained release of citral, which effectively inhibited the sprouting, leading to higher starch content by 41%, lower weight losses, reducing sugar content, α-Amylase, β-amylase, and starch phosphorylase activities by 75%, 55%, 34%, 31%, and 43%, respectively.

4.	Starvation 10/01/1990 - "Additionally, the in vitro activities of starch phosphorylase, ATP dependent phosphofructokinase, NAD dependent glyceraldehyde-3 phosphate dehydrogenase, and glucose-6 phosphate dehydrogenase did not seem to support carbon fluxes from starch to triose phosphates as calculated from the rate of starch disappearance during carbon starvation of the cells. "
