Part:BBa_K3332080

pBAD/araC promoter-cI repressor-terminator

It can express cI repressor under certain conditions.By using this part, we can make engineering bacteria survive at low formaldehyde concentration if we want.

Usage and Biology

The promoter BAD/araC is induced under arabinose and cI repressor is the co-protein of MazF, reduces the toxicity of MazF after their combination, provides the minimum margin of formaldehyde-induced cell toxicity.

Fig1. Circuit

Characterization

When we were building this circuit, we did the nucleic acid gel electrophoresis experiment to verify. After the circuit was built, we sent the plasmid to sequence, and got the correct sequencing. After new molecular cloning experiments, we did Enzyme-Cut identification to certify the plasmid is correct. We used the EcoR I and Pst I to cut the plasmid, then we got the target separate fragment-2148bp
