Crystallization (Comment) | Organism |

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 | Pseudomonas sp. AIU 813 |

D238A | the interaction of Asp238 with the terminal, positively charged group of the substrates is critical for substrate binding but not for catalytic control between the oxidase/monooxygenase activities | Pseudomonas sp. AIU 813 |
D238E | mutant displays increased catalytic activities | Pseudomonas sp. AIU 813 |
D238F | mutant exhibits altered substrate specificity to long hydrophobic substrates | Pseudomonas sp. AIU 813 |
