Description
This part is promoter of the TorCAD operon from Escherichia coli, and its expression only happens in response to Trimethylamine N-oxide (TMAO). The TMAO is a organic compound with the formula (CH3)3NO, and it is a metabolite produced by the liver in humans, but in bacteria TMAO is used to produce energy in the absence of oxygen. The TMAO binds to TorT protein, which activates the TorS protein. The TorS protein phosphorilates the TorR transcriptional factor, which binds to TorCAD promoter, activating the transcription.
