pDawn-RBS070-LKD-LVA-T1
Description
This composite part is a generator consisting of pDawn(cI-LVA)(BBa_K1075044),RBS070(BBa_K4325002), LKD-LVA (BBa_K4325011)and T1 terminator(BBa_K3257021).
Usage
We inserted the pDawn(cI-LVA) blue light response system (BBa_K1075044) and the lysis gene with hydrolysis tag LKD-LVA (BBa_K4325011) into the pSEVA331 expression vector, which was incorporated into E. coli TOP10 and screened for bacterial colonies that grew in the dark but did not grow under blue light. Finally, the plasmid containing pDawn (cI-LVA)-LKD-LVA-T1 were introduced into G. hansenii ATCC53582 by electroporation to verify the responsiveness of pDawn(cI-LVA) to blue light.

Characterization
1.Batch screening of pDawn(cI-LVA)-LKD-LVA-T1 in response to blue light lysis in E. coli.
As shown in Figure 1, the plasmid containing pDawn(cI-LVA)-RBS070-LKD-LVA-T1 was introduced into E. coli TOP10 and performed the agarose gel electrophoresis. Then we performed the drop plate assay in the dark and under blue light. After 12 hours, we found that the 4th, 5th, 6th, 14th bacterial colonies grew in the dark and did not grow under blue light, (Figure 2) which indicates that pDawn(cI-LVA)-RBS070-LKD-LVA-T1 functions as intended in .coli.
