Thus, the two substrates of this enzyme are alpha-D-glucose 1-phosphate and H2O, whereas its two products are D-glucose and phosphate.
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is alpha-D-glucose-1-phosphate phosphohydrolase. This enzyme participates in glycolysis and gluconeogenesis.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1NT4.
