Lxxvii. the Chemistry of Amino-acid Deamination
THE final phase of amino-acid metabolism, involving the removal of nitrogen from the amino-group and the production of urea, is generally regarded as involving two distinct processes: (1) deamination, with the liberation of ammonia, (2) dehydration of ammonium carbonate, with formation of urea. The change being represented as: R. CH(NH2) . COOH NH3 (NH4C03CON2H4 Now, while there is no doubt as ...
متن کاملOxidative deamination of S-adenosyl-L-homocysteine by rat kidney L-amino acid oxidase.
Cell-free extracts prepared from rat kidney or liver catalyzed the oxidative deamination of S-adenosyl-Lhomocysteine to S-adenosyl-y-thio-a-ketobutyrate. This reaction was found to be catalyzed by L-amino acid oxidase (L-amino acid:oxygen oxidoreductase (deaminating), EC 1.4.3.2). In the presence of catalase, 0.48 pmole of oxygen was consumed for each micromole of substrate oxidized, and 1 pmol...
متن کاملStabilization of D-Amino Acid Oxidase via Covalent Immobilization and Mathematical Model of D-Methionine Oxidative Deamination Catalyzed by Immobilized Enzyme
D-Amino acid oxidases (DAAOs) have an important role in several processes of interest in the fine chemical and pharmaceutical industry for drug discovery. They are used in the production of optically pure L-amino acids1 and unnatural amino acids2, and the production of 7-aminocephalosporanic acid (7-ACA)2,3 which is a precursor of antibiotics with annual demand of approximately 100 t worldwide3...
متن کاملOxidative deamination of azafulleroids into C60 by peracids.
Oxidation of azafulleroids with peracids regenerated C60 depending on the N-substituents. Alkyl-substituted azafulleroids preferred the oxidation of nitrogen to afford N-oxides as possible intermediates for C60 in moderate yields. Phenyl- and tosyl-substituted azafulleroids rather allowed the oxidation at the carbon cage. Theoretical calculations predicted the order of reactivity of azafulleroi...
متن کاملOxidative deamination of hydrolyzed fumonisin B(1) (AP(1)) by cultures of Exophiala spinifera.
Fumonisins are mycotoxins of world-wide distribution in maize infected by the fungus Fusarium verticillioides. They are highly toxic to certain livestock and are potential carcinogens. Exophiala spinifera, a black yeast fungus found on moldy maize kernels, was identified previously as capable of growing on fumonisin B1 as a sole carbon source and thus is a potential source for fumonisin detoxif...
