SoxR
SoxR is a transcription factor found in bacteria and is activated during superoxide or nitric oxide stress. SoxR protein in solution is a homodimer that contains two binuclear iron–sulfur clusters ([2Fe–2S]) which are then oxidized upon superoxide stress. In this form, the protein induces transcription through binding at SoxS promoter. Thus, in the presence of NO, SoxR activates transcription of the gene regulated by SoxS promoter (Hidalgo et al, 1998).
