Summary
Nitric oxide (NO) induces NO-detoxifying enzymes in Escherichia coli suggesting sensitive mechanisms for coordinate control of NO defense genes in response to NO stress. Exposure of E. coli to sub-micromolar NO levels under anaerobic conditions rapidly induces transcription of the NO reductase (NOR) structural genes. This protein is involved in the pathway nitric oxide reduction, which is part of Nitrogen metabolism. It also acts as a transcriptional activator for at least the norVW operon. It binds to the promoter region of norVW, to a consensus target sequence, GT-(N7)-AC, which is highly conserved among proteobacteria.
