molecular dynamics simulations of wild-type, and all reported amyotrophic lateral sclerosis-associated DAO mutants. The mutations disrupt several key interactions with the active site residues and decrease the conformational flexibility of active site loop comprising 216 to 228 residues, necessary for substrate binding and product release, mainly due to the distortion of critical salt bridge and hydrogen bond interactions compared with wild-type. DAO mutants have a lower binding affinity toward cofactor flavin adenine dinucleotide and substrate iminoserine than the wildtype |
