Enzyme Information

5.1.99.6
NAD(P)H-hydrate epimerase.
based on mapping to UniProt P40165
(1) (6R)-6-beta-hydroxy-1,4,5,6-tetrahydronicotinamide-adenine dinucleotide = (6S)-6-beta-hydroxy-1,4,5,6-tetrahydronicotinamide-adenine dinucleotide. (2) (6R)-6-beta-hydroxy-1,4,5,6-tetrahydronicotinamide-adenine dinucleotide phosphate = (6S)-6-beta-hydroxy-1,4,5,6- tetrahydronicotinamide-adenine dinucleotide phosphate.
-!- The enzyme can use either (R)-NADH-hydrate or (R)-NADPH-hydrate as a substrate. -!- Its physiological role is to convert the (R) forms to the (S) forms, which could then be restored to active dinucleotides by EC 4.2.1.93.
