Part:BBa_K4325024

pDawn(cl)-X174E-T1

Description

This composite part is a generator consisting of pDawn (without LVA tag) (BBa_K4325010) and X174E (BBa_K1835500).

Usage

We inserted the pDawn (without LVA tag) blue light response system (BBa_K4325010)with the lysis gene X174E (BBa_K1835500)into the pSEVA331 expression vector, which was inserted into E. coli TOP10. The bacterial colony that grew in the dark but did not grow under blue light were screened to verify the responsiveness of pDawn (without LVA tag) to blue light.

Characterization

1.Batch screening of pDawn(without LVA tag)-X174E-T1 in response to blue light lysis in E. coli.

Figure1. (1)pSEVA331-pDawn(cI-LVA)-X174E-LVA-T1; (2)pSEVA331-pDawn(cI)-X174E-T1; (3)pSEVA331-pDawn(cI-LVA)-RBS070-LKD-LVA-T1; (4)pSEVA331-pDawn(cI)-RBS070-LKD-T1 were constructed successfully.

<P>

Figure2. Growth condition of pSEVA331-pDawn(cI)-X174E-T1-TOP10 in dark and under light.

As shown in Figure 1, we successfully constructed pSEVA331-pDawn(cI)-X174E-T1 and transformed it into E. coli TOP10, selection a monoclonal colony and culturing in different growth conditions. As shown in Figure 2, the 9^th colony of pSEVA331-pDawn(cI)-X174E-T1-TOP10 grew in the dark, but did not grow under blue light.
