The gene of recombinant PmrCAB (DPP4) two-component and quorum sensing system

We replaced the Fe (III) sensitive domains Trp34 to Glu64 of the original PmrB with the core binding domain of DPP4 protein Gly260 to Asp330 to be stimulated by the S protein of MERS-CoV. After detecting the S protein of MERS-CoV, the sensor kinase PmrB autophosphorylates the highly conserved histidine residue, and then transfers the phosphate group to the conserved aspartate residue in its homologous reaction regulator PmrA. Then phosphorylated PmrA protein combined with promoter PmrC sequence to activate the expression of reporter gene.

In order to improve the sensitivity of detection, we have improved the above parts and added a quorum sensing system (Fig. 1).
