pDawn-LKD-T1

Description

This composite part is a generator consisting of pDawn(cI-LVA) (BBa_K1075044), LKD (BBa_K4325004) and T1 terminator (BBa_K3033016).

Usage

The blue light responsive system pDawn(cI-LVA)(BBa_K1075044) and the lysis gene LKD (BBa_K4325004) were inserted 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 pDawn(cI-LVA)-LKD-T1 plasmid were extracted and electroporated into G. hansenii ATCC53582, after which we verified the responsiveness of pDawn(cI-LVA) to blue light.

Characterization

1.Batch screening of pDawn-LKD-T1 by evaluating the response to blue light.

As shown in Figure 2, except for the 16th bacterial colony, almost all of the bacteria did not grow under blue light. To further show the lysis effect of pDawn(cI-LVA)-LKD-T1, we tracked the OD 600 values of pDawn(cI-LVA)-LKD-T1 and plotted the growth curves diagram. As shown in Figure 3, E. coli TOP10-pSEVA331-pDawn(cI-LVA)-LKD-T1 is not excellent.
