Aldose 1-epimerase

In enzymology, an aldose 1-epimerase (EC number|5.1.3.3) is an enzyme that catalyzes the chemical reaction

:alpha-D-glucose $ightleftharpoons$ beta-D-glucose

Hence, this enzyme has one substrate, alpha-D-glucose, and one product, beta-D-glucose.

This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on carbohydrates and derivatives. The systematic name of this enzyme class is aldose 1-epimerase. Other names in common use include mutarotase, and aldose mutarotase. This enzyme participates in glycolysis and gluconeogenesis.
