Schematic diagram for the process of constructing the small antibody and the fusion peptide. (a) The small antibody (the mimetic moiety) was composed of V_HFR1_C-10-V_HCDR1-V_HFR2-V_LCDR3-V_LFR4_N-10. (b, c) The mimetic was conjugated to the C-terminal of wild-type colicin Ia to construct the conjugated peptide, named protomimecin (PMN). (d) The 15% SDS- PAGE migration map of the fusion peptide PMN.
