tcdA1-device

OVERVIEW 

     We construct the device tcdA1 to tandem express toxic protein tcdA1 and reporter mCherry. Toxic protein tcdA1 is used to kill termites in our project. 
     tcdA1, one of the biggest proteins in bacteria, is first found in Photorhabdus luminescens. It forms channels and assists other toxins across the cell membrane1. It belongs to tc toxic protein family, which is widely distributed among different gram-negative and gram-positive bacteria. 
     We clone and standardize the gene into standard plasmid pSB1C3. After confirmation of digestion and sequencing, we transform the plasmid into E.coli BL21(DE3) to achieve better expression level. Despite we observe that transformants have obviously turned red, we didn’t figure out the expected protein band in SDS-PAGE. Judging that the protein is considerably huge in bacteria, more improvements are needed.
