Editor-In-Chief: Henry A. Hoff
"The trp promoter does not have a consensus Pribnow box sequence (T-T-A-A-C-T) but it does have a consensus -35 sequence (T-T-G-A-C-A)."[1]
The "degenerate -35 sequence, and the location of the Fis binding site, which forces a suboptimal 16 bp spacing between the -35 and -10 elements, allow only σs but not σ70 to function at proP (P2).[2]
Consensus sequences
"Two domains upstream of the start site of transcription have been identified for which a consensus sequence has been formulated (1-5). [One of these domains is] the -35 sequence (5'-T-T-G-A-C-A-3')".[1]
A1BG sampling
For the Basic programs (starting with SuccessablesM35.bas) written to compare nucleotide sequences with the sequences on either the template strand (-), or coding strand (+), of the DNA, in the negative direction (-), or the positive direction (+), the programs are, are looking for, and found:
- negative strand in the negative direction (from ZSCAN22 to A1BG) is SuccessablesM35--.bas, looking for 3'-TTGACA-5', 2, 3'-TTGACA-5', 477, 3'-TTGACA-5', 4399,
- negative strand in the positive direction (from ZNF497 to A1BG) is SuccessablesM35-+.bas, looking for 3'-TTGACA-5', 0,
- positive strand in the negative direction is SuccessablesM35+-.bas, looking for 3'-TTGACA-5', 0,
- positive strand in the positive direction is SuccessablesM35++.bas, looking for 3'-TTGACA-5', 0,
- complement, negative strand, negative direction is SuccessablesM35c--.bas, looking for 3'-AACTGT-5', 0,
- complement, negative strand, positive direction is SuccessablesM35c-+.bas, looking for 3'-AACTGT-5', 0,
- complement, positive strand, negative direction is SuccessablesM35c+-.bas, looking for 3'-AACTGT-5', 2, 3'-AACTGT-5', 477, 3'-AACTGT-5', 4399,
- complement, positive strand, positive direction is SuccessablesM35c++.bas, looking for 3'-AACTGT-5', 0,
- inverse complement, negative strand, negative direction is SuccessablesM35ci--.bas, looking for 3'-TGTCAA-5', 0,
- inverse complement, negative strand, positive direction is SuccessablesM35ci-+.bas, looking for 3'-TGTCAA-5', 0,
- inverse complement, positive strand, negative direction is SuccessablesM35ci+-.bas, looking for 3'-TGTCAA-5', 0,
- inverse complement, positive strand, positive direction is SuccessablesM35ci++.bas, looking for 3'-TGTCAA-5', 0,
- inverse, negative strand, negative direction, is SuccessablesM35i--.bas, looking for 3'-ACAGTT-5', 0,
- inverse, negative strand, positive direction, is SuccessablesM35i-+.bas, looking for 3'-ACAGTT-5', 0,
- inverse, positive strand, negative direction, is SuccessablesM35i+-.bas, looking for 3'-ACAGTT-5', 0,
- inverse, positive strand, positive direction, is SuccessablesM35i++.bas, looking for 3'-ACAGTT-5', 0.
