The regulatory role of MtrA and NsrR in streptomyces coelicolor
… MtrAB-LpqB and the nitrite-sensitive repressor NsrR. Previous work involving the response regulator MtrA has resulted in the hypothesis that MtrA regulates cell division within actinomycetes. However the role of MtrAB-LpqB within S. coelicolor has not been investigated. Therefore it is important …

Architecture of Escherichia coli promoters that respond to reactive nitrogen species
… hcp and ogt genes, namely NarL / NarP, FNR and NsrR. Transcription activation by NarL was then studied using semi-synthetic promoters. The hcp gene was found to be positively regulated by FNR and negatively regulated by NsrR. Contrary to previous reports, NarL and NarP were found to have little …

Biogenesis of iron-sulfur clusters and intracellular iron metabolism
… and nitrosative stress response pathways. NsrR, a nitric oxide (NO) sensitive transcriptional repressor, is shown to coordinate a redox active [2Fe-2S] cluster with a midpoint redox potential of -346 ± 7 mV. The NsrR [2Fe-2S] cluster reacts with NO more quickly than other [Fe-S] proteins, …

In planta studies of the corn pathogen Pantoea stewartii subsp. stewartii and applications of a corn-based industrial byproduct
… genes encoding seven transcription factors, nsrR, iscR, lrp, nac, DSJ_00125, DSJ_03645, and DSJ_18135, as well as a hypothetical protein DSJ_21690. Investigation of the physiological role of these genes was performed using in planta virulence and competition assays for all strains. An in …

Endogenous production and detoxification of a potent cytotoxin, nitric oxide, in Salmonella enterica serovar Typhimurium and Escherichia coli
… NosZ. Furthermore, the contribution of selected NsrR regulon genes, to endogenous N2O production of Salmonella was determined and revealed that HmpA and the Hcp-Hcr operon are both crucial for high N2O levels. These findings provide new insights into host-pathogen interactions, which could …

The Impact of Nitrite on Aerobic Growth of Paracoccus denitrificans PD1222
… flavohemoglobin (fhb; Pd1689) and its associated NsrR family, transcriptional regulator (Pd1690), were transcribed above a ≥2 fold expression filter (p ≤ 0.05) at 95% significance in qRT-PCR and a type II microarray transcriptional analysis at 12.5 mM nitrite in batch culture. Additionally, >25 …
