| Synonyms | CT1087, SQOR, SQR, Sqrdl, Suden_1879, Suden_2082, Suden_619, sulfide quinone oxidoreductase, sulfide quinone oxidoreductase::, sulfide quinone reductase, sulfide-quinone reductase, sulfide: quinone oxidoreductase, sulfide:decylubiquinone oxidoreductase, sulfide:quinone oxidoreductase, sulfidequinone reductase-like protein |
| EC Number | 1.8.5.4 |
| CAS Registry Number | |
| Comments | Contains FAD. Ubiquinone, plastoquinone or menaquinone can act as acceptor in different species. This enzyme catalyses the formation of sulfur globules. It repeats the catalytic cycle without releasing the product, producing a polysulfide of up to 10 sulfur atoms. The reaction stops when the maximum length of the polysulfide that can be accommodated in the sulfide oxidation pocket is achieved. The enzyme also plays an important role in anoxygenic bacterial photosynthesis. cf. EC 1.8.5.8, eukaryotic sulfide quinone oxidoreductase. |
| Cofactor | FAD |
| History | |
| Reactions | n sulfide + n quinone = polysulfide + n quinol. |
