Down-regulation of the Escherichia coli K-12 nrf promoter by binding of the NsrR nitric oxide-sensing transcription repressor to an upstream site.

Douglas F Browning1, David J Lee, Stephen Spiro, Stephen J W Busby.   

Abstract

FNR-dependent activation of the Escherichia coli K-12 nrf promoter is downregulated by the nitric oxide-sensitive NsrR protein together with the nucleoid-associated protein IHF, which bind to overlapping targets adjacent to the DNA site for FNR. The NsrR target is inactivated by mutation at the Salmonella enterica serovar Typhimurium nrf promoter.
