Arabinose inducible Reflectin A1-sfGFP fusion generator

E.coli transformed with this construct will produce a superfolder Green fluorescent Protein (sfGFP) fused variant of reflectin A1 under the control of pBAD, an arabinose inducible protein. There is currently (at the time of writing) no good assay for reflectin, in vivo. This construct allows reflectin to be localised within the cell. This part has been used to view reflectin containing inclusion bodies in E.coli and the sfGFP retained its fluorescence despite the fusion.

Usage and Biology

Cambridge 2011 used this part to assess reflectin folding on different backbones.

  • Reflectin-GFP on pSB1A3(a high copy plasmid), induced with 1mM Arabinose. Fluorescence is localised in dots at the end of the cells, indicating that fusion protein is localised to insoluble inclusion bodies.

  • Reflectin-GFP on pSB3K3 (low/med copy plasmid), induced with 1mM Arabinose. The fusion protein is distributed throughout the cytoplasm, indicating soluble protein is expressed.
