Strong RBS

To improve the RecA (K3) - B0034 - EGFP bioreporter we designed to test RecA(K3) (BBa_K3020001) promoter, we replaced the RBS with B0032 and a new RBS invented by Zhang, M. et al (2022). The researchers developed a machine learning model to predict the translation initiation rate of different RBS sequences. Then, the designed sequences were synthesized and experimentally tested for their translation initiation rates. However, our results indicated that Strong RBS did not improve performance of the reporter. Sequence: TTTAAGAGGGGGCTATACAT
