IH (INP-N-GFP-H)

Based on BBa_K1995008 (BH), we added INP-N and GFP to the upstream of BH. Using INP-N, we anchored GFP and BH out of the outer membrane of E.coli in order to increase the binding efficiency and using GFP to detect the concentration of cupric and mercuric ions.

Ice nucleation protein (INP) 

 We used INP to anchor GFP and BH out of the outer membrane of E. coli, firstly increasing the probability of the meeting of BH and heavy metal ions and secondly using the fluorescence quenching of GFP to detect the concentration of heavy metal ions.

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.

GFP reporter

GFP is an excellent reporter in synthetic biology. We add GFP into IH for following functions:

① Initial survey of the expression of IH.

② Detect the binding efficiency and other features of IH.

③ Detect and measure the concentration of cupric and mercuric ions.

Binding heavy metals

We detect the binding efficiency of IH and other parts and get the following chart. (Fig. 6)
