Mechanism of transcription termination: Role of chromatin and R-loops
La transcripción llevada a cabo por la ARN polimerasa II (RNAPII) es un proceso fuertemente regulado que se compone de tres fases: iniciación, elongación y terminación. De todas ellas, la terminación es la etapa menos estudiada y comprendida, sin embargo, de ella dependen procesos esenciales como …

The molecular mechanisms of transcription termination and pausing in the Escherichia coli threonine operon regulatory region
To study the mechanism of transcription termination at a rho-independent terminator, homoduplex and heteroduplex templates that contained mutations in the G + C-rich region of dyad symmetry in the Escherichia coli thr operon attenuator were constructed. Assays of these templates in an in vitro …

Transcription termination by bacteriophage T7 RNA polymerase at rho-independent terminators
To investigate the mechanism of transcription termination by bacteriophage RNA polymerases, templates encoding variants of the transcription-termination structure in the regulatory region of the threonine (thr) operon of Escherichia coli were used. The thr terminator comprises two distinct …

Factors and mechanisms of archaeal transcription termination and DNA repair
… health in dynamic environments. Regulation of RNA synthesis in response to internal and environmental stimuli is typically achieved through interactions with RNAP at all stages of the transcription cycle- initiation, elongation, and termination. While studies of transcription initiation and …

INVESTIGATING THE BASES OF THE SPECIFICITY OF THE RESTRICTOR COMPLEX FOR THE TERMINATION OF NONCODING TRANSCRIPTION
Rampant transcription initiation occurring at the tens of thousands of cis-regulatory regions in the genome can be detrimental to the normal functioning of the cell. Several transcription termination mechanisms act to keep the initiation of non-productive transcription in check. The Restrictor …
