PpspA-CDO1-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, CDO1.

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 CDO1. CDO1 converts L-cysteine into L-cysteine sulfonic acid in the taurine synthesis L-cysteine sulfinic acid pathway[2].

Usage

We ligased the PompA-ompA/oprF fragment and PpspA-cs on the pSU expression vector and transformed it into DH5α to complete construction of the plasmid.
