Lambert_GA 2019 Characterization
Characterization of Strong Promoter (BBa_J23119) and Strong RBS (BBa_B0034)
Differences in promoter strength had more effect on enzymatic expression compared to differences in RBS strengths as evidenced in the graphs below. Lambert_GA 2019 had originally thought that BBa_J10050 would result in the least amount of expression out of the tested combinations, but this part, along with BBa_J10051 and BBa_J10052, all shared the lowest expression out of the combinations. This is due to the translation rate not being an important factor in the determination of expression of ONP; however, the promoter strength is a significant factor. In other words, expression values are significantly different with different promoters but not with different RBS strengths.
Figure 1: The highlighted points in yellow represent BBa_J10058 (strong promoter/ strong RBS) compared to BBa_J10057 (strong promoter/ medium RBS) and BBa_J10056 (strong promoter/ weak RBS), both in light blue. The weak, medium, and strong RBS have similar expression levels when in combination with the weak promoter.
Figure 2: The highlighted points represent the BBa_J10058 composite part (strong promoter/ strong RBS). As the promoter strength increases, the expression increases as well.
The graphs above show that RBS strength has a negligible effect on expression, whereas increased promoter strength increases expression.
