In enzymology, a D-lactate dehydrogenase (cytochrome) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are (D)-lactate and ferricytochrome c, whereas its two products are pyruvate and ferrocytochrome c. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with a cytochrome as acceptor. The systematic name of this enzyme class is (D)-lactate:ferricytochrome-c 2-oxidoreductase. Other names in common use include lactic acid dehydrogenase, D-lactate (cytochrome) dehydrogenase, cytochrome-dependent D-(−)-lactate dehydrogenase, D-lactate-cytochrome c reductase, and D-(−)-lactic cytochrome c reductase. This enzyme participates in pyruvate metabolism. It employs one cofactor, FAD. This type of enzyme has been characterized in animals, fungi, bacteria and recently in plants . It is believed to be important in the detoxification of methylglyoxal through the glyoxylase pathway
