Accepted name: D-lactate dehydrogenase (acceptor)
Reaction: (R)-lactate + acceptor = pyruvate + reduced acceptor
Other name(s): D-2-hydroxy acid dehydrogenase; D-2-hydroxy-acid dehydrogenase; (R)-2-hydroxy-acid:acceptor 2-oxidoreductase
Systematic name: (R)-lactate:acceptor 2-oxidoreductase
Comments: The zinc flavoprotein (FAD) from the archaeon Archaeoglobus fulgidus cannot utilize NAD+, cytochrome c, methylene blue or dimethylnaphthoquinone as acceptors. In vitro it is active with artificial electron acceptors such as 2,6-dichlorophenolindophenol, but the physiological acceptor is not yet known.
