ID   1.12.98.4
DE   sulfhydrogenase.
AN   sulfur reductase.
CA   H2 + n sulfur = H(+) + hydrogen sulfide + (n-1) sulfur.
CC   -!- The enzyme from the hyperthermophilic archaeon Pyrococcus furiosus is
CC       part of two heterotetrameric complexes where the beta and gamma
CC       subunits function as sulfur reductase and the alpha and delta
CC       subunits function as hydrogenases (EC 1.12.1.3 and EC 1.12.1.4).
CC   -!- Sulfur can also be used as substrate, but since it is insoluble in
CC       aqueous solution and polysulfide is generated abiotically by the
CC       reaction of hydrogen sulfide and sulfur, polysulfide is believed to
CC       be the true substrate.
CC   -!- Formerly EC 1.97.1.3.
