In enzymology, D-2-hydroxy-acid dehydrogenase (EC 1.1.99.6) is an enzyme that catalyzes the chemical reaction

 
 
 
D-2-hydroxy-acid dehydrogenase
 
 
 
+ reduced acceptor
 

The two substrates of this enzyme are (R)-lactic acid and an electron acceptor. Its products are pyruvic acid and the corresponding reduced acceptor. [1] [2] [3] [4]

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 (R)-2-hydroxy-acid:acceptor 2-oxidoreductase. Other names in common use include D-2-hydroxy acid dehydrogenase, and (R)-2-hydroxy-acid:(acceptor) 2-oxidoreductase. It has 2 cofactors: FAD, and zinc.
