Abstract: Rho-dependent transcription termination is a well conserved process in bacteria. The Psu and YaeO proteins are the two established inhibitors of the ATP-dependent RNA helicase Rho protein of E. coli. Here we show a detailed… read more here.

Abstract: Transcription termination mediated by the ring-shaped, ATP-dependent Rho motor is a multipurpose regulatory mechanism specific to bacteria and constitutes an interesting target for the development of new antibiotics. Although Rho-dependent termination can punctuate gene expression… read more here.

Abstract: Abstract Transcriptional pause is essential for all types of termination. In this single-molecule study on bacterial Rho factor-dependent terminators, we confirm that the three Rho-dependent termination routes operate compatibly together in a single terminator, and… read more here.

Abstract: Abstract Riboswitches are regulatory elements that control gene expression by altering RNA structure upon the binding of specific metabolites. Although Bacillus subtilis riboswitches have been shown to control premature transcription termination, less is known about… read more here.

Abstract: BackgroundIn bacterial genomes, there are two mechanisms to terminate the DNA transcription: the “intrinsic” or Rho-independent termination and the Rho-dependent termination. Intrinsic terminators are characterized by a RNA hairpin followed by a run of 6–8 U… read more here.
