Dimethyl sulfide:cytochrome c2 reductase () is an enzyme with systematic name dimethyl sulfide:cytochrome-c2 oxidoreductase. It is also known by the name dimethylsulfide dehydrogenase (Ddh). 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. It is a heterotrimeric protein with three subunits, the Molybdopterin DdhA (), the [4Fe-4S] DdhB (), and the heme-binding DdhC (). The subunits share homology with other DMSO reductase family enzymes; one example with all three subunits mapped is ethylbenzene hydroxylase from Aromatoleum aromaticum ().SWISS-MODEL.
