In molecular biology flavocytochrome c sulfide dehydrogenase is an enzyme found in sulfur-oxidising bacteria such as the purple phototrophic bacteria Chromatium vinosum. These enzymes are dimers of a flavoprotein and a dihaem cytochrome that carry out hydrogen sulfide-dependent cytochrome C reduction. The dihaem cytochrome folds into two domains each of which resembles mitochondrial cytochrome c with the two haem groups bound to the interior of the subunit.
