PpspA-JJU
Description
This composite part is a component of the IFN-γ sensing system and was used to express the taurine production enzyme, JJU.
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.[1]Signal transduction from the outer membrane to the inner membrane activates the pspA promoter, initiating expression of JJU. JJU converts L-cysteine into L-cystate in the taurine synthesis L-cystate pathway.
Usage
We ligased the jju fragment and pspA promoter on the pSU expression vector and transformed it into DH5α to complete construction of the plasmid.
