A blue light regulated ccdb apoptosis gene

This is a composite of two units, a blue light promoter and a ccdb killing gene. The blue light promoter may turn on the transcription of ccdb.CcdB poisons the gyrase-DNA complex, blocking the passage of polymerases and leading to double-strand breakage of the DNA. Alternatively, in cells that overexpress CcdB, the A subunit of DNA gyrase (GyrA) has been found as an inactive complex with CcdB. The lethal effect of CcdB is most probably due to poisoning of the gyrase-DNA complex.

NYMU Biosafety picture8.jpgIndicated from the above graph, we could discover that after exposure to light for a period of time, the population of E. coli(transformed by ccdb suicide gene) dramatically decrease. And even the population of E. coli reached the stable stage, we can still attain 92.5%proportion of killing.

NYMU Biosafety picture7.jpgInferred from the above graph, we could discover that after exposure to light for a period of time, the survival rate of E. coli(transformed by ccdb suicide gene) dramatically decrease. And the less culture time, less time is needed to kill most of them (In 2hr survival rates are all below 1%). So we could conclude that our modified E. coli could be easily killed by exposure to light in a short upon released.
