Characteration

In 2019, UCAS-China made several improvements to CI434, BBa_C0056 by constructing a new part, CI434-TEVsite, . Firstly, we inserted the TEV protease recognition sequence between N-terminal and C-terminal of CI434 so that it can be cleaved by TEV and then lose activity, which can regulate gene expression at both transcriptional and proteolytic levels. As shown in Figure 1 and Figure 2, we can see that CI434-TEVsite and original TEV have little difference. However, when there exists TEV protease, CI434-TEVsite can lose its activity so that the genes expression under CI434-TEVsite can be activated significantly.
