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	Reaction=(6S)-NADHX + ATP = ADP + phosphate + NADH + H(+); Xref=Rhea:RHEA:19017, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:57945, ChEBI:CHEBI:64074, ChEBI:CHEBI:456216; EC=4.2.1.93;
CATALYTIC ACTIVITY	Reaction=(6S)-NADPHX + ATP = ADP + phosphate + NADPH + H(+); Xref=Rhea:RHEA:32231, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:57783, ChEBI:CHEBI:64076, ChEBI:CHEBI:456216; EC=4.2.1.93;
COFACTOR	Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
case <OC:Fungi>
SUBCELLULAR LOCATION	Cytoplasm.
else case <OC:Mammalia>
SUBCELLULAR LOCATION	Mitochondrion.
end case
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.
