Hydration of NAD(P)H to NAD(P)HX, which inhibits several dehydrogenases, is corrected by an ATP-dependent dehydratase and an epimerase. The ATP-dependent dehydratase has been identified as the product of the vertebrate Carkd (carbohydrate kinase domain) gene [1, 2]. Variants of this enzyme leads to deficient NADHX repair mitochondrial dysfunction in humans, associated with a lethal neurometabolic disorder in early childhood [2]. In E. coli, it is found as the C-terminal domain of a bifunctional enzyme (YjeF) that also includes the epimerase and uses ADP instead of ATP [3]. These enzymes are widespread in eukaryotes, prokaryotes, and archaea.	Domain
