| 1.13.12.2 | structures of L-AAO/MOG complexed with L-Lys, L-ornithine, and L-Arg. Residue Asp238 is located at the ceiling of a long hydrophobic pocket and forms a strong interaction with the terminal, positively charged group of the substrates. In the ligand-free structure, there are two channels connecting the active site and solvent, and a short region located at the dimer interface is disordered. In the L-Lys complex structure, a loop region is displaced to plug the channels |
