pDawn-RBS070-LKD-LVA-T1

Description

This composite part is a generator consisting of pDawn (cI-LVA) (BBa_K1075044) and LKD-LVA (BBa_K4325011).

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 inserted into E. coli TOP10 and screened for bacterial colony that grew in the dark but did not grow under blue light. Finally, the -LKD-LVA-T1-pSEVA331-pDawn (cI-LVA) -LKD-LVA-T1 plasmids were inserted into G. hansenii ATCC53582 by electroporation to verify the responsiveness of pDawn (cI-LVA) to blue light.

Characterization

1.Batch screening of pSEVA331-pDawn(cI-LVA)-LKD-LVA-T1 in response to blue light lysis in E. coli.

As shown in Figure 1, We inserted pSEVA331-pDawn (cI-LVA) -RBS070-LKD-LVA-T1 into E. coli TOP10 and performed the agarose gel electrophoresis. Then we cultured monocloning site in the dark and under thelight. After 12 hours, we found that the 4th, 5th, 6th, 14th bacteria grew in the dark and did not grow under the light,(Figure 2) which indicates that pSEVA331-pDawn (cI-LVA) -RBS070-LKD-LVA-T1 is successfully expressed in E. coli TOP10.
