CC -!- FUNCTION: Bifunctional enzyme that catalyzes the epimerization of the CC S- and R-forms of NAD(P)HX and the dehydration of the S-form of CC NAD(P)HX at the expense of ADP, which is converted to AMP. This allows CC the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that CC is a result of enzymatic or heat-dependent hydration. CC {ECO:0000256|ARBA:ARBA00025153, ECO:0000256|PIRNR:PIRNR017184}. 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:0000256|HAMAP-Rule:MF_01965}. CC -!- FUNCTION: Catalyzes the epimerization of the S- and R-forms of CC NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or CC heat-dependent hydration. This is a prerequisite for the S-specific CC NAD(P)H-hydrate dehydratase to allow the repair of both epimers of CC NAD(P)HX. {ECO:0000256|HAMAP-Rule:MF_01966}.
