PpspA-JJU-6xHis-PlacI-OmpA/OprF
Description
This composite part is a component of the IFN-γ sensing system and is used to express the taurine production enzyme, JJU10.
Biology
The LacI promoter facilitates the constitutive expression of OmpA/OprF. Binding of IFN-γ to the OmpA/OprF chimeric protein induces the response of the phage shock protein (Psp) system, a highly conserved stress response system in enterobacteria[1]. Signal transduction from the outer membrane to the inner membrane activates the pspA promoter, initiating expression of JJU10. JJU10 converts L-cysteine into L-cystate in the taurine synthesis L-cystate pathway.
Usage
We ligased the pLacI-OmpA* fragment and pspA-JJU10-his-tag on the pSU expression vector and transformed it into DH5α to complete construction of the plasmid. The his-tag allows for confirmation of JJU10 expression by western blot using the anti-6X his-tag antibody.
