Sigma factor binding site
WebThe -35 sequence (5’-TTGACA-3’ in the coding DNA strand) allows high transcription rates because it serves as part of the binding site for the sigma (σ) factor protein. The -35 sequence is located approximately 35 base pairs (bp) upstream of the transcription start site (+1 site).-10 sequence (Pribnow box).

WebDec 15, 2009 · Region 2 is the most highly conserved region in bacterial σ-factors (4, 7) and can be further subdivided into regions 2.1, 2.2, 2.3, and 2.4.Amino acids in regions 2.1 and 2.2 form a pair of α-helices that mediate core binding by virtue of interaction with a coiled-coil element in the amino terminus of the β′-subunit of core RNAP (). WebThe gene transcription of bacteria starts with a promoter sequence being recognized by a transcription factor found in the RNAP enzyme, this process is assisted through the conservation of nucleotides as well as other factors governing these intergenic regions. Faced with this, the coding of genetic information into physical aspects of the DNA such …
