J23104+B0032+INP+YFP

Ice nucleation protein(INP)is a secretory outer membrane protein from Pseudomomas syringae P. flurorescens and several other Gram—negative bacteria.In the bacterial surface display technology,INP is widely used as a functional carrier protein.

Design

We got the INP from (BBa_K523013) constructed by iGEM11_Edinburgh. To test the surface display efficiency of INP, we add YFP to the downstream of INP, and expressed the fusion protein under the control of (J23104) and (B0032) .

Microscopy result

We observed the fluorescence under the super-resolution microscope. As figure 1 shows, The intracellular expression of sfGFP displayed the rode-shape of E.coli, while the signal of surface displayed YFP showed the dotted pattern, which suggested that the YFP were gathered and distributed at the surface of E.coli..
