Design Notes

The UTEX 2385 M. aeruginosa strain used in our project was not available as an organism for the Salis RBS Library Calculator v2.1.1 [1-3]. We instead used the PCC 7806 strain. Since the two strains have similar 16S rRNA sequences and the anti-Shine-Dalgarno sequence is found at the 3' end of the 16S rRNA sequence, we expect the estimated TIR based on the 7806 strain to be a reasonable approximation of the TIR in the UTEX 2385 strain since it is the anti-Shine-Dalgarno sequence on the ribosome that interacts with the RBS on the mRNA transcript.

This synthetic RBS was generated with specified inputs into the Salis RBS Library Calculator v2.1.1. The protein CDS used was our Microcystis-optimized eGFP (BBa_K4592001). The organism used was PCC 7806 M. aeruginosa. The target minimum TIR was 5000 and target maximum TIR was 1000000.
