ENZYME entry: EC 1.8.5.4
Accepted Name |
bacterial sulfide:quinone reductase.
|
Alternative Name(s) |
sulfide:quinone reductase. |
Reaction catalysed |
n a quinone + n H(+) + n hydrogen sulfide <=> n a quinol + n sulfur |
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.
