Comments [?]

Function Catalyzes the dehydration of the S-form of NAD(P)HX at the expense of ATP, which is converted to ADP. Together with NAD(P)HX epimerase, which catalyzes the epimerization of the S- and R-forms, the enzyme allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration.
Catalytic activity RHEA:19017: (6S)-NADHX + ATP = ADP + H(+) + NADH + phosphate
EC 4.2.1.93
Cofactor Mg(2+)

case <OC:Mammalia> and not <AnyFeature:TransitM>
Miscellaneous This protein may be expected to contain an N-terminal transit peptide but none has been predicted.
end case
Similarity Belongs to the NnrD/CARKD family.
