showing functionally divergent sites with selection pressure in AaeUPO a) showing the residues which interact with aromatic rings in polycyclic aromatic hydrocarbons, and b) showing other relevant sites. The surface area represents binding pocket and residue sites are represented as small spheres. Orange spheres show Type-I functional divergence sites, green spheres indicate positive selection, blue spheres indicate the sites with positive selection and Type-I functional divergence, red spheres represent the predicted specific residues responsible for functional divergence in UPOs, yellow spheres indicate residues with positive selection+functional divergence+predicted critical residue and magenta colored spheres indicate negative selection
