Composite
Part:BBa_K3771022
Designed by: KAO, YI-CHING Group: iGEM21_NCKU_Tainan (2021-10-01)
PpspA-CoaBC
Description
This composite part is a component of the IFN-γ sensing system and was used to express the taurine production enzyme, CoaBC.
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 CoaBC. CoaBC converts L-cystate into taurine in the taurine synthesis L-cystate pathway.
Usage
We ligased the coaBC fragment and pspA promoter on the pSU expression vector and transformed it into DH5α to complete construction of the plasmid.
