SoxS promoter

SoxS is a promoter regulated by the SoxR transcription factor, which is activated by NO. E. coli can naturally respond to redox signals through a superoxide stress system composed by SoxR gene, SoxS promoter and the genes associated with 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 red box in the following schema:
