PpspA-CoaBC-6xHis-PompA-OmpA/OprF


Description


This composite part is a component of the IFN-γ sensing system and was used to express the taurine production enzyme, CoaBC.


Biology


The ompA 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 CoaBC. CoaBC converts L-cystate into taurine in the taurine synthesis L-cystate pathway.


Usage


We ligased the NPO-OmpA* fragment and pspA-CoaBC-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 CoaBC expression by western blot using the anti-6X his-tag antibody.


Characterization


Double digestion results are shown in Fig. 2.
