Design Notes

We optimized original RBS sequence of P1G1 to AGGAGGU, the consensus RBS sequence predicted to initiate high rate of translation according to the RBS calculator. Simultaneously, as we positioned RNA controller 1G1 upstream of GFP coding sequence by standard assembly, the spacing between RBS and AUG strat codon is ACUAG (scar generated during standard assembly). The modification of RBS sequence and spacing between RBS and AUG start codon had inappreciable influence on the core secondary stem-loop structure of functional original riboswitch and almost preserves the quondam base-pairing region.

Use mutagenesis PCR of BBa_K598007 to alter RBS sequence. Engineered RBS is selected from constitutive library based on RBS calculator.
