Comments
[?]
| FUNCTION | Catalyzes the dehydration of the S-form of NAD(P)HX at the expense of ADP, which is converted to AMP. Together with NAD(P)HX epimerase, which catalyzes the epimerization of the S- and R-forms, the enzyme allows the repair of both epimers of NAD(P)HX, a damaged form of NAD(P)H that is a result of enzymatic or heat-dependent hydration. |
| CATALYTIC ACTIVITY | Reaction=(6S)-NADHX + ADP = AMP + phosphate + NADH + H(+); Xref=Rhea:RHEA:32223, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474, ChEBI:CHEBI:57945, ChEBI:CHEBI:64074, ChEBI:CHEBI:456215, ChEBI:CHEBI:456216; EC=4.2.1.136; |
| CATALYTIC ACTIVITY | Reaction=(6S)-NADPHX + ADP = AMP + phosphate + NADPH + H(+); Xref=Rhea:RHEA:32235, ChEBI:CHEBI:15378, ChEBI:CHEBI:43474, ChEBI:CHEBI:57783, ChEBI:CHEBI:64076, ChEBI:CHEBI:456215, ChEBI:CHEBI:456216; EC=4.2.1.136; |
| COFACTOR | Name=Mg(2+); Xref=ChEBI:CHEBI:18420; |
| SUBUNIT | Homotetramer. |
| SIMILARITY | Belongs to the NnrD/CARKD family. |
