Abstract:
We describe a proteomic approach to identify transcription factors binding to a target promoter. The method's usefulness was tested by identifying proteins binding to the Vibrio cholerae rpoS promoter in response to cell density. Proteins identified in this screen included the nucleoid-associated protein Fis and the quorum sensing regulator HapR.

Transcription Elongation Factors
The transcription elongation is regulated via pausing of RNA polymerase on several occasions during transcription. In bacteria, these halts are necessary because the transcription of DNA into mRNA is coupled to the translation of that mRNA...

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
