In wild type lambda phage, the OR3 site (-27 to -11) reads "tatcccttgcggtgata" on the sense strand of DNA. To prevent lambda repressor (cI) from binding to this site, the 4th through 10th nt of OR3 were replaced by the 7 nt between OR2 and OR1, "aaatagt" (-57 to -51), which in effect mutates 5 nt of the promoter. These nt were chosen to be about halfway between the -10 and -35 boxes of the promoter. Furthermore, since these nt already act as a spacer in wild-type phage, it is hoped they will not create undesired interactions.

The O-R3 region of the lambda cI strand was mutated by 7 nt to eliminate any binding in the region. This was not replaced with the O-R1 region of p22 due to the fact that the O-R1 site had a length of 18 nt, while the space between the -10 and -35 regions was only 16 nt. Thus, spacing would not be preserved, and this could cause many problems. However, since p22 cI must still repress the production of the lambda cI protein, the OR-1 site of p22 was still placed within the construct. The positioning is right after the -10 region (between the -10 region and the RBS). Thus, when p22 cI binds in, protein production should still be inhibited, whereas, if p22 does not bind in, there will just be a little extra code in the mRNA, which theoretically should not cause any problems.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.
