Z3C is derived from three helix 58-residue Z-domain of staphylococcal protein A, but it has three helix. Z3C also shows great affinity with VEGF(KD=41 nM). We used pBBR plasmid as a backbone and transfered Z3C into Escherichia coli Nissle 1917, and finally succeeded in expressing Z3C.

pBBR-OmpA-Z3C

Just like miniZ, Z3C is also derived from three helix 58-residue Z-domain of staphylococcal protein A, but it has three helix. Z3C also shows great affinity with VEGF(KD=41 nM).

We used pBBR1MCS-2 plasmid as a backbone and transfered Z3C into Escherichia coli Nissle 1917, and finally succeeded in expressing Z3C.
