arcB Antibody

1. The authors observed that wild-type, DeltaarcA, and DeltaarcB had comparable initial NO* clearance times; however, the mutant cultures failed to exhibit [NO*] and [O2 ] oscillations. these results establish ArcAB as a TCS that influences NO* detoxification in E. coli within the physiologically-relevant microaerobic regime. PMID: 28449226
2. Data show that the redox potential of ArcB is about -41 mV, and we demonstrate that the menaquinols are required for proper ArcB activation upon a shift from aerobic to anaerobic growth conditions. PMID: 23645604
3. These analyses revealed that elimination of different segments in ArcB determines a distinctive distribution of d-glucose catabolic fluxes, different from that observed in the DeltaarcB background. PMID: 23064346
4. The results lead to the working hypothesis that the in vivo activity of ArcB in E. coli is modulated by the redox state of the menaquinone pool and that the ubiquinone/ubiquinol ratio in vivo surely is not the only determinant of ArcB activity. PMID: 19933363
5. the ArcB/ArcA/RssB system is involved in sigma(S) induction during entry into starvation conditions. PMID: 16291649
6. An active form of ArcB promotes low-level induction of psp expression independent of pIV and communicates with PspB. PMID: 19682256
7. Both ArcA and ArcB were necessary for resistance to hydrogen peroxide, and their function in this resistance was independent from H2O2 scavenge. PMID: 19715602
