pBBR-INP-ZVEGF
This work is derived from pBBR1MCS-INP-mCherry and PUC19-ZVEGF-V114-V107-peptide, and it has undergone codon optimization. This composite part combines INP(about 30kda) and ZVEGF(approximately 6kda), we succeeded in transferring this plasmid into Escherichia coli Nissle 1917 and let it express ZVEGF. The plasmid uses lac promotor and has kanamycin resistence.
ZVEGF is a 59-residue three-helix peptide that was developed by Fedorova et al. by randomizing 9 residues on helices 1 and 2 of the Z-domain scaffold via phage display, followed by selection for binding to the VEGF8-109 dimer. A co-crystal structure of ZVEGF with VEGF8-109 shows that the engineered Z-domain adopts the expected three-helix bundle tertiary structure and engages the receptor-recognition sites on the VEGF dimer through a surface formed by helices 1 and 2 of ZVEGF. It shows great affinity with VEGF(Ki=0.41 μM).We used pBBR1MCS-2 plasmid as a backbone and transfered ZVEGF into Escherichia coli Nissle 1917, and finally succeeded in expressing ZVEGF.
