| 5.1.3.2 | NAD+ |
1.78 mol of NAD+ per dimer. Each subunit is independently capable of being associated with one molecule of NAD+, suggestive of two NAD+ binding sites of epimerase per dimer |

| 5.1.3.2 | NAD+ |
coenzyme is tightly bound at the active site. NAD+ functions as the coenzyme for the interconversion of UDP-galactose and UDP-glucose by reversibly mediating their dehydrogenation to the common intermediate UDP-4-ketohexopyranoside. NAD+ activation induced by uridine nucleotides is brought about by a conformational change of epimerase that repositions Tyr149 at an increased distance from nicotinamide N1 of NAD+ while maintaining the electrostatic repulsion between Lys153 and nicotinamide N1 of NAD+ |
