Many genomes of anaerobic hyperthermophiles encode multiple homologs of NAD(P)H oxidase that are thought to function in response to oxidative stress. We investigated one of the seven NAD(P)H oxidase homologs (TK1481) in the sulfur-reducing hyperthermophilic archaeon Thermococcus kodakarensis, focusing on the catalytic properties and roles in oxidative-stress defense and sulfur-dependent energy conservation. The recombinant form of TK1481 exhibited both NAD(P)H oxidase and NAD(P)H:polysulfide… CONTINUE READING
