PpspA-CS-6xHis


Description

This composite part is a component of the IFN-γ sensing system and was used to express the taurine production enzyme, L-cysteine sulfonic acid synthase (CS).

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 CS. CS converts o-phospho-l-serine into L-cysteine sulfonic acid in the taurine synthesis L-cysteine sulfinic acid pathway[2].

Usage

We ligased the CS-his-tag fragment and pspA promoter on the pSU expression vector and transformed it into DH5α to complete construction of the plasmid. The his-tag allows for confirmation of CS expression by western blot using the anti-6X his-tag antibody.

Characterization

Double digestion results are shown in Figure 1.
