Design Notes

Detect and remove possible restriction sites: XbaI, EcoRI, PstI, SpeI, AgeI, BamHI, BglII, NogMIV, NotI and XhoI. No restriction site had to be removed. Sequence starts 3 bp before the IHF binding site and ends 6 pb after the -10 box.


Source

Genomic sequence from biocyc, Escherichia coli K-12. Native unmodified sequence.
