Dimethyl sulfide:cytochrome c2 reductase (EC 1.8.2.4, Ddh (gene)) is an enzyme with systematic name dimethyl sulfide:cytochrome-c2 oxidoreductase.[1][2] This enzyme catalyses the following chemical reaction

dimethyl sulfide + 2 ferricytochrome c2 + H2O dimethyl sulfoxide + 2 ferrocytochrome c2 + 2 H+

The enzyme from the bacterium Rhodovulum sulfidophilum binds molybdopterin guanine dinucleotide, heme b and [4Fe-4S] clusters.
