pDawn-RBS070-LKD-T1
Description
This composite part is a generator containing pDawn(cI-LVA) (BBa_K1075044), RBS070 (BBa_K4325002), LKD (BBa_K4325004) and T1 terminator(BBa_K3033016).
Usage
We inserted the blue light responsive system pDawn(cI-LVA) (BBa_K1075044) and lysis gene LKD (BBa_K4325004) into the pSEVA331 expression vector, which was incorporated into E. coli TOP10 and screened for the bacterial colonies which grew in the dark but did not grow under blue light. Finally, the plasmids containing pDawn(cI-LVA)-RBS070-LKD-T1 were selected and introduced into G. hansenii ATCC53582 by electroporation to verify the responsiveness of pDawn(cI-LVA) to blue light.

Characterization
1.Batch screening of pDawn-RBS070-LKD-T1 by evaluating the response to blue light.
As shown in Figure 2, except for the 11th and 13th bacterial colonies, other bacterial colonies did not grow under blue light. To further explore the lysis effect of pDawn(cI-LVA)-RBS070-LKD-T1-TOP10, we tracked the OD600 values of pDawn(cI-LVA)-RBS070-LKD-T1-TOP10 and plotted the growth curves diagram. As shown in Figure 3, the lysis effect of pDawn(cI-LVA)-RBS070-LKD-T1-TOP10 meets our expectation in the first eight hours, but it is unstable after fifteen hours.
