WebNov 7, 2016 · Transcription is the first and most heavily regulated step in gene expression. Sigma (σ) factors are general transcription factors that reversibly bind RNA polymerase (RNAP) and mediate transcription of all genes in bacteria. σ Factors play 3 major roles in the RNA synthesis initiation process: they (i) target RNAP holoenzyme to specific promoters, … WebAug 14, 2024 · It indicates the protein: sigma factor PvdS and gene: PvdS.

This DNA sequence is found about 30 base pairs upstream of the transcription … WebDec 15, 2009 · Abstract. The σ-like factor YvrI and coregulator YvrHa activate transcription from a small set of conserved promoters in Bacillus subtilis. We report here that these two proteins independently contribute σ-region 2 and σ-region 4 functions to a holoenzyme-promoter DNA complex. YvrI binds RNA polymerase (RNAP) through a region 4 interaction …
WebA L97R substitution in the VP1 capsid protein of enterovirus A71, conferring heparan sulfate binding ability, was detected in an immunocompromised patient.
