Some kinetic parameters of platelet monoamine oxidase in chronic schizophrenia. 1979

R D Kobes, and S G Potkin, and C D Wise, and T P Bridge, and L M Neckers, and R J Wyatt

The michaelis constants (Vmax and Km) for platelet monoamine oxidase (MAO) with tyramine as substrate are found to be significantly lower in chronic schizophrenic patients than in normal controls. Furthermore, these kinetic parameters for the MAO of paranoid chronic schizophrenics are significantly lower than those for nonparanoid chronic schizophrenics. Paranoid chronic schizophrenia may be a separate biochemical disorder from other chronic schizophrenias.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008995 Monoamine Oxidase An enzyme that catalyzes the oxidative deamination of naturally occurring monoamines. It is a flavin-containing enzyme that is localized in mitochondrial membranes, whether in nerve terminals, the liver, or other organs. Monoamine oxidase is important in regulating the metabolic degradation of catecholamines and serotonin in neural or target tissues. Hepatic monoamine oxidase has a crucial defensive role in inactivating circulating monoamines or those, such as tyramine, that originate in the gut and are absorbed into the portal circulation.
