Catalyzes the oxidation of D-lactate to pyruvate. Electrons derived from D-lactate oxidation are transferred to the ubiquinone/cytochrome electron transfer chain, where they may be used to provide energy for the active transport of a variety of amino acids and sugars across the membrane. (R)-lactate + a quinone = a quinol + pyruvate Inhibited by 2-hydroxy-3-butynoic acid, but not by p-chloromercuribenzoate, n-ethylmaleimide, or 5,5'-dithiobis(2-nitrobenzoic acid). May bind the membrane through electrostatic rather than hydrophobic forces. Contains 3 domains: the flavin adenine dinucleotide (FAD)-binding domain, the cap domain and the membrane-binding domain. Belongs to the quinone-dependent D-lactate dehydrogenase family. Truncated N-terminus.
