Design Notes

The spytag has been placed on the N terminal of the sfGFP. This is because we were unsure if the spytag/spycatcher isopeptide bond would still be formed if the spytag was in the centre of the protein. However, we were unsure if this design would affect the insertion of OmpA into the membrane. An alternative part [BBa_K2450451] with the opposite design has been created so the spytag is in the centre of the protein, so we are more confident in the insertion of OmpA into the membrane but less confident in the isopeptide bond formation.

sfGFP rather than GFP has been used as this part is being targeted to the outer membrane, and GFP cannot fold in the periplasmic space.
