PlacI-OmpA/OprF

Description

PlacI-ompA/oprF is part of the IFN-γ sensing system. lacI promoter regulates the constitutive expression of OmpA/OprF.

Biology

When there is no lac repressor, the lacI promoter facilitates the constitutive expression of OmpA/OprF. In the IFN-γ sensing system, binding of IFN-γ to the OmpA/OprF chimeric protein activates the pspA promoter, producing the enzyme required for the synthesis of taurine.

Usage
We ligased ompA/oprF gene and the PlacI expression vector pSU and transformed it into DH5α to complete construction of the plasmid. Then, the plasmid was purified and transformed into E. coli ompA mutant strain JW0940.

Characterization

PCR


Western blot was performed to confirm the expression of OmpA/OprF
