EC 1.8.5.4     
Accepted name: sulfide:quinone reductase
Reaction: n HS- + n quinone = polysulfide + n quinol
Systematic name: sulfide:quinone oxidoreductase
Comments: Contains FAD. Ubiquinone, plastoquinone or menaquinone can act as acceptor in different species. This enzyme catalyses the formation of sulfur globules. It is also an important step in anoxygenic bacterial photosynthesis.
