Improvement by SDU_CHINA 2019

Our team has optimized the BBa_S04615 part. The improved part is BBa_K3127995.

In 2018, the SDU-CHINA team optimized the K592001 part to reduce its leakage under the red light. We have improved its promoters this year, which has further bettered the performance of this component.

The component BBa_K2627000 proved the progress of the optimized CcaS by sufficient characterization, so we directly replaced BBa_K592001 in BBa_S04615 with the optimized K2627000 when characterizing this component. In 2014, Schmidl S R , Sheth R U, Wu A, et al. optimized CcaS by constructing an RBS library. This document has fully proven that the performance of components with optimized RBS is better than S04615. In 2019, our team SDU-CHINA has further improved the components based on them. We have introduced site-directed mutagenesis to the improved promoter, further bettering the performance based on all previous studies.
