In bacteria, the Rho protein mediates Rho-dependent termination (RDT) by identifying a non-specific cytosine-rich Rho utilization site on the newly synthesized RNA. As a result of RDT, downstream RNA transcription is reduced. Due to the bias in reverse transcription and PCR ...

In bacteria, the transcription process ends via two types of termination pathways, namely, intrinsic or factor-independent and Rho-dependent termination1. InE. coli, a large number of transcription termination events are Rho-dependent1. Rho is a homo-hexameric RNA-dependent ATPase that binds to na...
The N protein of phage lambda prevents termination of transcription by Escherichia coli RNA polymerase at Rho-dependent and -independent terminators in the lambda early operons. The modification of RNA polymerase by N requires an N-utili... SW Mason,J Li,J Greenblatt - 《Journal of Biological ...
rho-Independent Transcription Termination 来自 Springer 喜欢 0 阅读量: 190 作者: WP Library 摘要: Also it is called intrinsic transcription termination. The original model visualized the involvement of an RNA hairpin followed by a 15-nucleotide T (thymidine-rich) region. The hairpin may be......
Rho-Dependent Termination The best characterized termination factor is the bacterial ρ protein.ρ is a classic termination factor in the sense that it provides a mechanism for dissociating nascent transcripts at sites that lack intrinsic terminators. Rho is essential for the survival of most bacteria...
In others, such as Bacillus subti- lis, Rho homologs play a smaller role, and Rho-independent termination is the norm. Detection of transcription termination sites is key to under- standing the operon structure of bacterial genomes. Under- standing the operons, in turn, gives us strong hints...
Transcription is crucial for the expression of genetic information and its efficient and accurate termination is required for all living organisms. Rho-dependent termination could rapidly terminate unwanted premature RNAs and play important roles in bact
3′ Processing 6S RNA Rho-dependent Termination ssrS ygfA Introduction Small noncoding RNAs (sRNAs)3 mediate a number of cellular processes in bacteria, such as protein tagging for degradation, modulation of RNA polymerase activity, regulation of mRNA stability and translation, and secretion (1, 2...
All show substantial RNA-dependent ATPase activity with several homoribopolymers or the lambda cro message as cofactor. At the lambda tR1 Rho-dependent terminator in vitro, all mutant Rho proteins show decreased termination compared with wild-type, and all also terminate within cro at a new ...
