Architecture of dual transcriptional-translational control systems. Blue and pink arrows indicate transcription and translation, respectively. (A) HYZEL. RF1, peptide release factor 1. (B) RiboTite(tT/tT). (C) cymO/R and theophylline riboswitch control. P21, synthetic P21 promoter. cmt, operator sequence of the cumate degradation operon. CymR, CymR regulator. TheoRS, theophylline riboswitch. (D) cymO/R and theophylline ribozyme control. TheoRZ, theophylline ribozyme. (E) Transcriptional terminator and occluded RBS control. PrepC, promoter regulating repC. TT + oRBS, transcriptional terminator and occluded RBS. repC-N, first 12 nucleotides of repC. (F) Transcriptional terminator and anti-toxin mRNA antisense RNA control. PCON, a constitutive promoter. TT, transcriptional terminator. asTOX, antisense RNA against the RBS-start codon region of toxin gene mRNA.
