Transcription factor NNR from Paracoccus denitrificans is a sensor of both nitric oxide and oxygen: isolation of nnr* alleles encoding effector-independent proteins and evidence for a haem-based sensing mechanism.

Abstract excerpt

The nitrite reductase and nitric oxide reductase regulator (NNR) from Paracoccus denitrificans activates transcription in response to nitric oxide (NO). The mechanism of NO sensing has not been elucidated for NNR, or for any of its orthologues from the FNR/CRP family of transcriptional regulators. Using regulated expression of the nnr gene in Escherichia coli, evidence has now been obtained to indicate that...
