CC -!- FUNCTION: Catalyzes the dehydration of the S-form of NAD(P)HX at the
CC expense of ATP, which is converted to ADP. Together with NAD(P)HX
CC epimerase, which catalyzes the epimerization of the S- and R-forms, the
CC enzyme allows the repair of both epimers of NAD(P)HX, a damaged form of
CC NAD(P)H that is a result of enzymatic or heat-dependent hydration.
CC {ECO:0000256|HAMAP-Rule:MF_03157}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6S)-NADHX + ATP = ADP + H(+) + NADH + phosphate;
CC Xref=Rhea:RHEA:19017, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,

CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03157};
CC -!- SIMILARITY: Belongs to the NnrD/CARKD family. {ECO:0000256|HAMAP-
