Q8U195 and Q8U194
NADH is not utilized as an electron donor for polysulfide reduction. Polysulfide reduction is catalyzed with reduced ferredoxin as an electron donor. However, the rate of sulfide production, at least in vitro, is much lower than when the enzyme uses NADPH to provide reductant for polysulfide reduction
