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