ENZYME - 1.12.98.4 sulfhydrogenase

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