In enzymology, a beta-phosphoglucomutase (EC 5.4.2.6) is an enzyme that catalyzes the chemical reaction
- beta-D-glucose 1-phosphate
beta-D-glucose 6-phosphate
Hence, this enzyme has one substrate, beta-D-glucose 1-phosphate, and one product, beta-D-glucose 6-phosphate.
This enzyme belongs to the family of isomerases, specifically the phosphotransferases (phosphomutases), which transfer phosphate groups within a molecule. The systematic name of this enzyme class is beta-D-glucose 1,6-phosphomutase. This enzyme participates in starch and sucrose metabolism.
Structural studies
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1LVH, 1O03, 1O08, 1Z4N, 1Z4O, and 1ZOL.
