Figure 2. Examples of proteins with potentially allosteric OTH binding sites.
Proteins are represented in cartoon format. The monomer structure with identified binding sites is in white. SiteMap binding sites are shown as spheres, bound ligands are shown as ball-and-sticks. A, SULT2B1 (PDB: 1q1q.A) with an ENZ binding site occupied by a nucleotide and three additional OTH binding sites (green, blue, yellow). B, RET (PDB: 2iiv.A) with an ENZ binding site occupied by the bound inhibitor and an additional OTH binding site (green). C, CHP2 (PDB: 2bec.A) with two PPI binding sites (green, blue) at the interface with SL9CA1 (PDB: 2bec.B) and an additional OTH binding site (peach). D, The superimposed structure of PLAUR (PDB: 1ywh.M) with two PPI binding sites at the interfaces with VTN (PDB: 3bt1.B, green) and PLAU (PDB: 3bt1.A, yellow) and an additional OTH binding site (peach).
