Table 3 Comparison of residues at the binding site of A. tumefaciens (At) OccJ and NocT and S. enteratica (Se) LAO. Residues in bold show those that are different between OccJ, NocT and LAO. * are residues interacting with the ligand through hydrophobic stacking, van der Waals contacts and/or hydrogen bonding. Residues in italics  and underlined are the binding signature for the pyruvate moiety of octopine in OccJ and the ketoacid moiety of octopine/nopaline in NocT, respectively.
