pDawn-RBS070-X174E-T1

Description

This composite part is a generator consisting of pDawn(cI-LVA)(BBa_K1075044) and X174E(BBa_K1835500).

Usage

The pDawn (cI-LVA)(BBa_K1075044) blue light response system and the lysis gene X174E(BBa_K1835500) were inserted into the pSEVA331 expression vector,which wsa inserted into the E.coli TOP10,screened out bacterial colony that grew in the dark but did not grow under blue light. Finally, the pSEVA331-pDawn-RBS070-X174E-T1 plasmid was inserted into G. hansenii ATCC53582 to verify the responsiveness of pDawn(cI-LVA) to blue light.

Characterization

1.Batch screening of pSEVA331-pDawn(cI-LVA)-RBS070-X174E-T1 in response to blue light lysis in E. coli.

As shown in Figure 2, the 11^th and 15 ^th bacterial colony did not grow under blue light but grow in dark. In order to further explore the lysis effect of pSEVA331-pDawn (cI-LVA)-RBS070-X174E-T1-TOP10, we measured the OD₆₀₀ value of pSEVA331-pDawn (cI-LVA)-RBS070-X174E-T1-TOP10 periodically andploting the growth curve diagram.As shown in Figure 3, the lysis effect of pSEVA331-pDawn (cI-LVA)-RBS070-X174E-T1-TOP10 is not well.

2.pSEVA331-pDawn(cI-LVA)-RBS070-X174E-T1 in response to blue photolysis in G. hansenii ATCC53582.

pDawn(cI-LVA)-RBS070-X174E-T1 was inserted into G. hansenii ATCC53582 by electroporation and identified. As shown in Figure 4, pDawn(cI-LVA)-RBS070-X174E-T1 was successfully inserted into G. hansenii ATCC53582.
