Gene transcriptions/Boxes/Pribnow

From Wikiversity

"Although the first five bases of the conserved sequence are identical to the first five bases of the Pribnow box (TATAA), the sixth base of the Pribnow box is a 100 per cent conserved T (refs 15-17) while the 100 per cent conserved A found here is actually more similar to eukaryotic promoter sequences20."[1]

"Two domains upstream of the start site of transcription have been identified for which a consensus sequence has been formulated(1-5). These domains are the -35 sequence (5'-T-T-G-A-C-A) and the Pribnow box (5'-T-A-T-A-A-T) in the -10 region. Both domains are in close contact with the RNA polymerase during initiation of RNAsynthesis (2,6)."[2]
