Chimeric FFV/PFV Bet proteins. (A) Schematic structure of FFV Bet and PFV Bet (blue shading). Conserved motifs are represented as gray boxes for FFV Bet and black boxes for PFV Bet. The Bel1part consists of 31 amino acids in FFV Bet and 88 amino acids in PFV Bet. FFV Bet contains 387 amino acids and PFV Bet, 482 amino acids. (B) FFV-PFV CH1 to CH6 are chimeras of N-terminal parts of PFV Bet and central and C-terminal parts of FFV Bet. (C) FFV-PFV CH7 to 11 are chimeras of N-terminal parts of FFV Bet and central and C-terminal parts of PFV Bet. White shading represents FFV Bet-derived sequences and blue shading, PFV Bet. Numbers indicate positions of the first and the last amino acid derived from PFV and FFV Bet. For example, CH1 is composed of the first 39 residues of PFV Bet and residues 33–378 of FFV Bet. A green box at the end of each protein represents the V5 tag.
