RRlocked

This part is half of a two-part killswitch-system for E.coli utillizing a riboregulator for posttransciptional regulation of hokD. It consists of the fused sequences of a constitutive promoter (BBa_J23100), a cis-repressing sequence, hokD (BBa_K1497008) and a terminator (BBa_B0015). When transcribed the cis-repressing sequence forms a hairpin-secondary-structure masking the ribosome binding site (RBS) and therefore prevents translation of the following hokD-sequence. If the corresponding trans-activating RNA-sequence (RRKey-BBa_K1602049) is present the two sequences form a RNA-RNA-complex. This leads to a helix shift and the release of the RBS enabling the expression of hokD killing the bacteria.
