Summary

Description
Catalyzes two distinct but analogous reactions: the reversible epimerization of UDP-glucose to UDP-galactose and the reversible epimerization of UDP-N-acetylglucosamine to UDP-N-acetylgalactosamine (PubMed:20519568, PubMed:22654673). The reaction with UDP-Gal plays a critical role in the Leloir pathway of galactose catabolism in which galactose is converted to the glycolytic intermediate glucose 6-phosphate. It contributes to the catabolism of dietary galactose and enables the endogenous biosynthesis of both UDP-Gal and UDP-GalNAc when exogenous sources are limited (PubMed:22654673). Both UDP-sugar interconversions are important in the synthesis of glycoproteins and glycolipids.
Catalytic Activity
UDP-alpha-D-glucose = UDP-alpha-D-galactose
UDP-N-acetyl-alpha-D-glucosamine = UDP-N-acetyl-alpha-D-galactosamine
Cofactor
NAD(+)
Subunit
Homodimer.
Similarity
Belongs to the NAD(P)-dependent epimerase/dehydratase family.
