Recombinant Escherichia coli Transcription termination factor Rho (rho)

1. Our findings further show that the RNA sequence specificity used for guiding Rho-dependent termination derives in part from an intrinsic ability of the motor to couple the recognition of pyrimidine patterns in nascent transcripts to RNA loading and activity. PMID: 27821776
2. results, together with existing data, support a model in which the connector segment plays a hitherto overlooked role in the regulation of Rho-dependent termination PMID: 28559482
3. Translational control and Rho-dependent transcription termination are intimately linked in riboswitch regulation. PMID: 28520932
4. NusG acts as both a positive and negative regulator of Rho in the course of the bacterial transcription termination. (Review) PMID: 27023849
5. Finally, identification of the NusG binding sites on the Rho hexamer led us to conclude that the former exerts its effect allosterically. PMID: 27605667
6. Rho inhibition leads to RNA polymerase readthrough, which in principle could displace H-NS from the DNA, thus leading to transcriptional derepression of H-NS-silenced genes. PMID: 24499790
7. Rho binds C-rich unstructured nascent RNA (high C/G ratio) prior to its ATP-dependent dissociation of transcription complexes PMID: 23207917
8. Tthe in vivo Rho-dependent termination process is kinetically controlled. PMID: 22442304
9. Here the authors provide direct evidence that the beta-sheet bundle of the C-terminal domain of NusG (NusG-CTD) has the binding determinants for Rho. PMID: 21040729
10. The authors mutated E211, R366, R212, and D265, and characterized the resulting proteins for oligomerization, ligand binding and RNA-dependent ATP hydrolysis that support the existing model of ATP hydrolysis. PMID: 20950626
11. Global hydrogen-deuterium exchange indicate net mass differences of about 15 Da after 1 h of exchange in the presence--versus in the absence--of the ligand MgATP or the RNA poly(C). PMID: 20708016
12. Results indicate that all three Rho catalytic sites must be filled with substrate to achieve the enhanced catalytic rate, both in pre-steady-state and in steady-state hydrolysis. PMID: 15703177
13. Results reinforce the importance of catalytic cooperativity in normal Rho function and suggest that several protein conformations exist along the catalytic pathway. PMID: 15703178
14. findings show that transcription termination of fimE is Rho dependent and is suppressed in a rho mutant or by bicyclomycin treatment when fimE mRNA is expressed by the fimE gene, either from a recombinant plasmid or in its native chromosomal location PMID: 16321930
15. mutant forms of Rho were defective in transcriptional termination, suggesting that those residues play an important role in the activation of Rho by bound RNA PMID: 16908525
16. interactions in the primary RNA binding domain and in the Q-loop are mandatory for RNA release to occur and propose that the interactions in the primary RNA binding modulate most of the other functions of Rho allosterically PMID: 17599352
17. results reveal Rho factor as a global regulator of gene expression under normal growth conditions; it serves role of maintaining transcriptional boundaries; Rho termination, supported by NusA & NusG, is required to suppress toxic activity of foreign genes PMID: 18487194
18. ADP but not P(i) dissociation contributes to rate limitation for Escherichia coli Rho PMID: 19837672
19. These data show that Rho forms uneven productive interactions with the track nucleotides and disrupts RNA-DNA duplexes in a succession of large (approximately 7-nucleotide-long) discrete steps triggered by 2'-hydroxyl activation events. PMID: 19915588
