RNA-OUT S4 It is amongst the mutant library of RNA-OUT, part of 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. Earlier studies have suggested that the 5 base pairs in the 5’ end of RNA-IN and in the loop domain of RNA-OUT determine the initiation of RNA duplex formation. The mutation of these 5 base pairs resulted in a library of orthogonal RNA regulators of translation. The translation repression rate of these regulators and the cross-talk of them are shown as followed:
