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).

Usage and Biology

This promoter is used by [http://2011.igem.org/Team:UNICAMP-EMSE_Brazil/Project/Device2 UNICAMP-EMSE Brazil team] in the NO sensor device ("Device 2", which senses NO levels and responds by producing and secreting IL-10. This part is shown in the following schema:
