Figure 1

Three-dimensional structures of pig OBP (PDB: 1E06, Vincent et al., 2000), Bombyx mori PBP1 (PDB: 1DQE, Sandler et al., 2000), and Mamestra brassicae CSP2 (PDB: 1N8U, Campanacci et al., 2003), representative examples of a vertebrate OBP, an insect OBP and an insect CSP, respectively. Proteins of these three classes, despite marked structural differences, perform similar roles of transport and solubilization of semiochemicals and are extremely compact and stable. Structures have been visualized using the Swiss-Model PDB Viewer (Guex and Peitsch, 1997).
