ENZYME entry: EC 1.8.5.4
| Accepted Name |
|---|
| Bacterial sulfide:quinone reductase.
|
| Alternative Name(s) |
|---|
| Sulfide:quinone reductase. |
| Reaction catalysed |
|---|
| n sulfide + n quinone <=> polysulfide + n quinol |
| Cofactor(s) |
|---|
| FAD.
|
| Comment(s) |
|---|
- Ubiquinone, plastoquinone or menaquinone can act as acceptor in
different species.
- This enzyme catalyzes 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.
