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|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}.
