PpspA-CDO1


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

Usage

We ligased the cs fragment and pspA promoter on the pSU expression vector and transformed it into DH5α to complete construction of the plasmid.
