Other name(s): ddh (gene name)
Systematic name: (R)-2-hydroxycarboxylate:NADP+ oxidoreductase
Comments: This enzyme, characterized from the halophilic archaeon Haloferax mediterranei, catalyses a reversible stereospecific reduction of 2-ketocarboxylic acids into the corresponding D-2-hydroxycarboxylic acids. The enzyme prefers substrates with a main chain of 5 carbons (such as 4-methyl-2-oxopentanoate) to those with a shorter chain, and can use NADH with much lower efficiency. cf. EC, (D)-2-hydroxyacid dehydrogenase (NAD+).
