scFv-intimin and intimin molecular structure. Constructed models based on the predicted structures of conserved intimin and recombinant anti-intimin scFv. A. Conserved intimin (int388-667) [GenBank:CAS11487]. B. Anti-intimin scFv (heavy chain in green, light chain in blue and linker in yellow). C. Interaction between conserved intimin and anti-intimin scFv as predicted by the programs ZDOCK and Rosetta Dock.
