Studies on the stability of the choline oxidase.
The choline oxidase was first described by Bernheim and Bernheim (1). Later it was shown (2) that choline at pH 6.7 was oxidized to betaine aldehyde which was then only slowly oxidized further, whereas at pH 7.8 the oxidation proceeded rapidly to betaine. This indicated that betaine aldehyde was oxidized by another enzyme system, and Klein and Handler (3) were able to show that its oxidation re...
متن کاملFurther studies with xanthine oxidase inhibitors.
The osidase and dehydrogenase activities in the enzymes oxidizing xanthine can be differentiated by the use of certain inhibitors (1). The present study was designed to see if such inhibitors are specific for the reaction with oxygen, or whether these agents also block the transfer of electrons to cytochrome c and nitrate. Both reduced diphosphopyridine nucleotide and hypoxanthine were studied ...
متن کاملFurther studies on the synthesis of A-form monoamine oxidase.
The relation between precursors and restoration of A-form MAO activity in rat liver after administration of clorgyline to rats was investigated by measuring the rates of recovery of A-form MAO activity after treatment with the inhibitor. The half-lives of mitochondrial and microsomal A-form MAO were estimated as 3.5 and 2.0 days, respectively. MAO activity and the amount of MAO molecules were c...
متن کاملA Novel Choline Biosensor Based on Immobilization of Enzyme Choline Oxidase on the β-Ga2O3 Nanowires Modified Working Electrode
This article is a report on a novel and high-stability biosensor with minor interference effects of surface modification of working electrode with β-Ga2O3 nanowires (NWs) on choline oxidase biosensor were investigated in an electrochemical detection system. β-Ga2O3 NWs were materialized on the silicon substrate in a catalyst-free growth mechanism. The β-Ga2O<sub...
متن کاملStudies on choline dehydrogenase. II. Components of the choline oxidase system and the site of action of amytal.
Rat liver choline dehydrogenase has been known for many years to be one of the “cytochrome-reducing dehydrogenases” (1). Although it is functionally and structurally linked to the respiratory chain and acts without the mediation of readily dissociable coenzymes (2)) the cytochrome components linking choline dehydrogenase to oxygen have not been established. The purpose of this investigation was...
