aldose 1-epimerase superfamily; Aldose 1-epimerases or mutarotases are key enzymes of carbohydrate metabolism; they catalyze the interconversion of the alpha- and beta-anomers of hexose sugars such as glucose and galactose. This interconversion is an important step that allows anomer specific metabolic conversion of sugars. Studies of the catalytic mechanism of the best known member of the family, galactose mutarotase, have shown a glutamate and a histidine residue to be critical for catalysis; the glutamate serves as the active site base to initiate the reaction by removing the proton from the C-1 hydroxyl group of the sugar substrate and the histidine as the active site acid to protonate the C-5 ring oxygen.

galactose mutarotase_like; Galactose mutarotase catalyzes the conversion of beta-D-galactose to alpha-D-galactose. Beta-D-galactose is produced by the degradation of lactose, a disaccharide composed of beta-D-glucose and beta-D-galactose. This epimerization reaction is the first step in the four-step Leloir pathway, which converts galactose into metabolically important glucose. This epimerization step is followed by the phosophorylation of alpha-D-galactose by galactokinase, an enzyme which can only act on the alpha anomer. A glutamate and a histidine residue of the galactose mutarotase have been shown to be critical for catalysis, the glutamate serves as the active site base to initiate the reaction by removing the proton from the C-1 hydroxyl group of the sugar substrate, and the histidine as the active site acid to protonate the C-5 ring oxygen. Galactose mutarotase is a member of the aldose-1-epimerase superfamily.

Aldose 1-epimerase, similar to Lactococcus lactis lacX; Proteins similar to Lactococcus lactis lacX are uncharacterized members of aldose-1-epimerase superfamily. Aldose 1-epimerases or mutarotases are key enzymes of carbohydrate metabolism, catalyzing the interconversion of the alpha- and beta-anomers of hexose sugars such as glucose and galactose. This interconversion is an important step that allows anomer specific metabolic conversion of sugars. Studies of the catalytic mechanism of the best known member of the family, galactose mutarotase, have shown a glutamate and a histidine residue to be critical for catalysis; the glutamate serves as the active site base to initiate the reaction by removing the proton from the C-1 hydroxyl group of the sugar substrate, and the histidine as the active site acid to protonate the C-5 ring oxygen.
