CC   -!- FUNCTION: Catalyzes the dehydration of the S-form of NAD(P)HX at the
CC       expense of ADP, which is converted to AMP. 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:0000255|HAMAP-Rule:MF_01965}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(6S)-NADHX + ADP = AMP + H(+) + NADH + phosphate;
