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 (By similarity).
CC {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6S)-NADHX + ADP = AMP + H(+) + NADH + phosphate;
CC Xref=Rhea:RHEA:32223, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474,
