MeSH Heading
Starch Phosphorylase
Tree Number(s)
D08.811.913.400.450.460.400.374
Unique ID
D024941
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D024941
Scope Note
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.
