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}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-NADHX = (6S)-NADHX; Xref=Rhea:RHEA:32215,
CC ChEBI:CHEBI:64074, ChEBI:CHEBI:64075; EC=5.1.99.6;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01966};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-NADPHX = (6S)-NADPHX; Xref=Rhea:RHEA:32227,
CC ChEBI:CHEBI:64076, ChEBI:CHEBI:64077; EC=5.1.99.6;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01966};
CC -!- COFACTOR:
CC Name=K(+); Xref=ChEBI:CHEBI:29103;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01966};
CC Note=Binds 1 potassium ion per subunit. {ECO:0000256|HAMAP-
CC Rule:MF_01966};
CC -!- SIMILARITY: Belongs to the NnrE/AIBP family. {ECO:0000256|HAMAP-
CC Rule:MF_01966}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01966}.
