Therefore, while bacteria accomplish transcription of all genes using a single kind of RNA polymerase, the use of different sigma factor subunits provides an extra level of control. Eukaryotic ...

By tethering RNA polymerase with the coupling transcription factor NusG or its paralog or version, RfaH, which threads the ...

Transcription factors include a wide number of proteins, excluding RNA polymerase, that initiate and regulate the transcription of genes. One distinct feature of transcription factors is that they ...

This manuscript characterizes a mutated clone of RNA polymerase I in yeast, referred to as SuperPol, to understand the mechanisms of RNA polymerase I elongation and termination. The authors present ...

This process of protein synthesis occurs in two stages - transcription and translation ... by an enzyme (helicase enzyme). The enzyme RNA polymerase attaches to the DNA in a non-coding region ...

Citrullination, a transformative protein post-translational modification, is gaining recognition for its wide-ranging impact on cellular function and human disease.
