CC (INP-N-GFP-CC)

Based on BBa_K1995018 (BCC), we added INP-N and GFP to the upstream of BCC. Using INP-N, we anchored GFP and BCC 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 BCC out of the outer membrane of E. coli, firstly increasing the probability of the meeting of BCC 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 CC for following functions:

① Initial survey of the expression of CC.

② Detect the binding efficiency and other features of CC.

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

Binding heavy metals

We detect the binding efficiency of CC and other parts and get the following chart. (fig.2 Hg2+ binding efficiency of PC, CC, CCW)
