Abstract
The gene ( sipA ) encoding the sulfur-induced protein A (PF2025) is highly upregulated during growth of Pyrococcus furiosus on elemental sulfur (S 0 ). Expression of sipA is regulated by sulfide, the product of S 0 reduction, but in an iron-dependent manner. SipA is proposed to play a role in intracellular iron sulfide detoxification.Keywords
