Mitochondrial Monoamine Oxidase
Inhibitions of the relatively highly purified flavoenzyme, bovine kidney mitochondrial monoamine oxidase, previously described in Paper I (Erwin, V. G., and Hellerman, L., J. Biol. Gem., 242, 4230 (1967)), by several agents of current interest have been investigated. The inhibitors include Nmethyl-N-(Z-propynyl)benzylamine (pargyline), (+)-fransphenylcyclopropylamine (d form of tranylcypromine)...
متن کاملStudies on monoamine oxidase. (Report XXV). Effects of alcohols on beef liver mitochondrial monoamine oxidase.
The effects of alcohols on MAO activity in beef and rat liver mitochondria were studied. MAO activity was determined manometrically using tyramine (1× 10-2 M) as substrate and expressed as O2 uptake in 60 min. At concentrations of 0.1 to 10%, methanol and ethanol increased MAO activity in both beef and rat liver mitochondria. Activation of MAO by ethanol was reversib...
متن کاملMitochondrial Monoamine Oxidase
Monoamine oxidase of bovine kidney mitochondria has been purified to high specific activity by solubilization with digitonin, ammonium sulfate fractionation, and calcium phosphate gel-cellulose column chromatography. Absorption and fluorescence spectra indicated strongly that mitochondrial monoamine oxidase is a flavoenzyme. Under anaerobic conditions, benzylamine reduced the flavin at 460 rnp ...
متن کاملHuman Plasma Monoamine Oxidase
Although this human plasma enzyme was shown (1) to have certain characteristics in common with plasma amine oxidases from other mammals (2-6), it could be distinguished from these other plasma enzymes by its substrate specificity. During studies relating to the substrate specificity of the human enzyme, the oxidation of aliphatic amines was noted to have a number of distinctive kinetic features...
متن کاملHuman Plasma Monoamine Oxidase
Amine oxidases that occur in the plasma of mammals have been intensively studied in recent years (l-8). The ability of human plasma and serum to convert benzylamine to benzaldehyde has recently been demonstrated (9). Evidence has been presented to show that this enzymatic activity is different from other human plasma enzymes that catalyze the oxidation of amines (i.e. ceruloplasmin and diamine ...
