PpspA-JJU


Description
This composite part is a component of the IFN-γ sensing system and was used to express the taurine production enzyme, JJU10.

Biology
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.[3] 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 JJU10 fragment and pspA promoter on the pSU expression vector and transformed it into DH5alpha to complete construction of the plasmid.
