EC 1.8.1.18     
Accepted name: NAD(P)H sulfur oxidoreductase (CoA-dependent)
Reaction: hydrogen sulfide + NAD(P)+ = sulfur + NAD(P)H + H+
Other name(s): NADPH NSR; S0 reductase; coenzyme A-dependent NADPH sulfur oxidoreductase
Systematic name: hydrogen sulfide:NAD(P)+ oxidoreductase (CoA-dependent)
Comments: This FAD-dependent enzyme, characterized from the archaeon Pyrococcus furiosus, is responsible for NAD(P)H-linked sulfur reduction. The activity with NADH is about half of that with NADPH. The reaction is dependent on CoA, although the nature of this dependency is not well understood.
