R1051-OUT S1
The RNAOUTS1 is from a well-known antisense RNA-mediated translation control system in E. coli called RNA-IN-RNA-OUT.It derived from the copy-number control element from the insertion sequence IS10, wherein the RNA-OUT inhibits transposase expression. RNA-OUT base pairs to the translation initiation region of the transposase mRNA (RNA-IN), thereby repressing translation both by preventing ribosome binding and by promoting transcription degradation. The 5’ end of the unstructured, unstable sense RNA-IN is complementary to the top of the loop domain and to one entire side of the stable RNA-OUT hairpin. The translation repression rate between RNAOUTS1 and RNAIN S1 is 90%.
The cI regulated promoter is a strong promoter based on the pR promoter from bacteriohage lambda. The promoter has two DNA binding sites for lambda cI repressor BBa_C0051. cI binding results in repression of transcription.
