All denitrifiers can keep the steady-state concentrations of nitrite and nitric oxide (NO) below cytotoxic levels by controlling the expression of denitrification gene clusters by redox signalling through transcriptional regulators belonging to the CRP (cAMP receptor protein)/FNR (fumarate and nitrate reductase regulator) superfamily.

Keywords:
dissimilative nitrate respiration regulator (DNR), denitrification, cAMP receptor protein/fumarate and nitrate reductase regulator superfamily (CRP/FNR superfamily), nitric oxide, Pseudomonas aeruginosa, transcriptional regulation
