| 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. |
