1 The neurotoxicant 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) has been shown to generate reactive oxygen species during its interaction with monoamine oxidase type B (MAO-B). 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine monoamine oxidase B Homo sapiens
2 The neurotoxicant 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) has been shown to generate reactive oxygen species during its interaction with monoamine oxidase type B (MAO-B). 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine monoamine oxidase B Homo sapiens
3 The neurotoxicant 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) has been shown to generate reactive oxygen species during its interaction with monoamine oxidase type B (MAO-B). 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine monoamine oxidase B Homo sapiens
4 The neurotoxicant 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) has been shown to generate reactive oxygen species during its interaction with monoamine oxidase type B (MAO-B). 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine monoamine oxidase B Homo sapiens
5 The kinetic parameters, Km and Vmax, for MAO-B-catalyzed oxidation of MPTP to the corresponding species MPDP+ were found to be 0.194 mM and 0.335 microM/min, respectively. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine monoamine oxidase B Homo sapiens
6 Catalase, a scavenger of hydrogen peroxide (H2O2), inhibited the DMPO-OH spin adduct formation in a dose-dependent manner, indicating that H2O2 is produced in the MAO-B catalyzed oxidation of MPTP. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine monoamine oxidase B Homo sapiens
7 These data suggest that superoxide radicals are produced during the oxidation of MPTP by MAO-B and that the generation of H2O2 and .OH was secondary to the production of .O2-. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine monoamine oxidase B Homo sapiens
