5.1.3.2	epimerization	The reaction mechanism of UGE is thought to occur via transfer of the 4'-OH hydrogen of the sugar to the nicotinamide ring of noncovalently bound NAD+, rotation of the resulting 4'-ketopyranose intermediate in the active site, and transfer of the hydride from the nicotinamide ring of NADH back to C-4 of the sugar.	674580

5.1.3.2	additional information	HvUGE also catalyses the interconversion of UDP-GalNAc and UDP-GlcNAc, although it is not known if this has any biological significance.	-, 661017
