Abstract 1. (1) Amphibian monoamine oxidase differes markedly from the corresponding enzyme in mammalian tissue suspensions in at least two respects. In the first place it is progressively inactivated when shaken in oxygen at 37°C without added substrate, though its ability is greatly increased by reducing the incubation temperature to 25°C. Secondly, monoamine oxidase activity of suspensions of amphibian liver is noncompetitively inhibited by semicarbazide; the degree of inhibition varying… Expand

The reaction of sulfhydryl reagents with bovine hepatic monoamine oxidase. Evidence for the presence of two cysteine residues essential for activity.
The inactivation experiments with these sulfhydryl reagents, the protection experiments, and the kinetics as well as physicochemical observations suggest that there are only two cysteine residues that are required for activity of the enzyme. Expand

In the fish and amphibian species a wide range of thermostability was found which appeared to be correlated with the normal thermal environments of the animals, and at least in the frog enzyme stability was not altered by acclimating the animals to different temperatures. Expand

Experimental evidence is presented which suggests that EDTA may have a direct action on succinic dehydrogenase which leads to this enzyme becoming resistant to thermal inactivation at the reaction temperatures employed. Expand
Funtional Similarities between the Cytoplasmic Organelles of Melanocytes and the Mitochondria of Hepatocytes
The sharp structural differences between the respective liver cells evoked interest in comparing the functions of the organelles which abound in each, and abnormal metabolism of melanins is being encountered in human diseases ranging from neoplasia to extrapyramidal disorders of the brain. Expand

Inhibition of amine oxidase by metal ions and by sulphydryl compounds.
Intravenous administration to rats of mercuric acetate, cadmium chloride, lead acetates, and manganese sulphate, all being in vitro inhibitors of amine oxidase did not affect the enzyme activity of brain and liver in acute experiments. Expand
The oxidation of tryptamine by rat liver and other tissue suspensions.
Consistent and marked changes were found in the ultraviolet absorption spectrum of the tryptamine solutions, which have been utilized for the measurement of monoamine oxidase activity by the "substrate disappearance" method. Expand

These results confirm the conclusion that iproniazid is superior to choline- p -tolyl ether as an inhibitor of monoamine oxidase in vivo and that inhibition by pentamidine is noncompetitive, and in vivo brain monoamines oxidase activity is not easily inhibited. Expand
