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

Characterization
1.Batch screening of pSEVA331-pDawn(cI-LVA)-RBS070-LKD-T1 in response to blue light lysis in E. coli TOP10.
As shown in Figure 2,except for the 11th and 13th bacterial colony,almost all of the bacterial colony did not grow under blue light. To further explore the lysis effect of pSEVA331-pDawn (cI-LVA) -RBS070-LKD-T1-TOP10, we measured the OD 600 values of pSEVA331-pDawn (cI-LVA) -RBS070-LKD-T1-TOP10 and ploting the growth curve diagram. As shown in Figure 3, the pSEVA331-pDawn (cI-LVA) -RBS070-LKD-T1-TOP10 lysis effect was well in the first eight hours, but was unstable after fifteen hours.
2.pSEVA331-pDawn(cI-LVA)-RBS070-LKD-T1 in response to blue photolysis in G. hansenii ATCC53582.
As shown in Figure 3, we successfully indicated the pDawn (cI-LVA) -RBS070-LKD-T1 into G. hansenii ATCC53582 by electroporation.
