2-oxo-acid reductase

In enzymology, a 2-oxo-acid reductase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are (2R)-hydroxy-carboxylate and acceptor, whereas its two products are 2-oxo-carboxylate and reduced acceptor.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with other acceptors. The systematic name of this enzyme class is (2R)-hydroxy-carboxylate:acceptor oxidoreductase. Other names in common use include (2R)-hydroxycarboxylate-viologen-oxidoreductase, HVOR, and 2-oxoacid reductase.
