Schematic representation of fusion protein expression vector pBJR-2. ApR, ampicillin resistance gene; ColE1, origin of DNA replication; c-myc, sequence encoding the c-myc epitope; His6, hexa-histidine encoding sequence; P/O, lac wild-type promoter/operator; rbs, ribosome-binding site; pelB, signal peptide sequence of bacterial pectate lyase; VH, variable heavy chain; VL, variable light chain; rapLR1, Rana pipiens liver ribonuclease 1; H71, framework 3 residue 71; G4S, spacer connecting the ribonuclease with the scFv; (G4S)3, linker connecting the variable domains. Restriction sites for cloning are indicated.
