PHG (INP-N-HG)

 Based on BBa_K1995000 (BHG), we added INP-N to the upstream of BHG. Using INP-N, we anchored BHG out of the outer membrane of E.coli in

order to increase the binding efficiency of cupric and mercuric ions.

Ice nucleation protein (INP)

 To increase the binding efficiency and detect the concentration of heavy metals, we used INP to anchor BHG out of the outer membrane of

E. coli.

 Ice nucleation protein (INP) is an excretion surface protein. It is widely used for establishing germ surface display system. It contains

an internal repeated domain (IRD) and an N-terminal anchoring domain (fig.1). Studies have shown that decrease the time of repetition of IRD can also get a better-off rate of displaying. So we decreased the time of repetition of IRD to reduce pressure of synthesis of E. coli.
