The reaction of choline dehydrogenase with some electron acceptors.
1. The choline dehydrogenase (EC 1.1.99.1) WAS SOLUBILIZED FROM ACETONE-DRIED POWDERS OF RAT LIVER MITOCHONDRIA BY TREATMENT WITH Naja naja venom. 2. The kinetics of the reaction of enzyme with phenazine methosulphate and ubiquinone-2 as electron acceptors were investigated. 3. With both electron acceptors the reaction mechanism appears to involve a free, modified-enzyme intermediate. 4. With s...
متن کاملThe reaction of mitochondrial L-3-glycerophosphate dehydrogenase with various electron acceptors.
1. The kinetics of the reaction of glycerophosphate dehydrogenase with a variety of electron acceptors have been investigated. 2. In all cases the reaction mechanism appears to involve a free modified-enzyme intermediate. 3. With some electron acceptors, the maximum velocity of the reaction and the K(m) for glycerophosphate are independent of the nature of the electron acceptor, whereas in othe...
متن کاملCatalytic reaction of cytokinin dehydrogenase: preference for quinones as electron acceptors.
The catalytic reaction of cytokinin oxidase/dehydrogenase (EC 1.5.99.12) was studied in detail using the recombinant flavoenzyme from maize. Determination of the redox potential of the covalently linked flavin cofactor revealed a relatively high potential dictating the type of electron acceptor that can be used by the enzyme. Using 2,6-dichlorophenol indophenol, 2,3-dimethoxy-5-methyl-1,4-benzo...
متن کاملFactors limiting the histochemical reaction of choline dehydrogenase activity.
~ 113-The histochemical reaction of choline dehydrogenase was completely inhibited by the pretreatment of cryostat sections with either absolute acetone or lO<yo water-in-acetone at room temperature (25°C). The temperature of the organic solvents was critical in the inhibition of the staining for choline dehydrogenase. As the temperature was lowered, the inhibitory effects of the pretreatment d...
متن کاملGenetic Variation of Choline Dehydrogenase Gene in Idiopathic Male Infertility
Infertility can be caused by an unexplained reduction in semen quality in males who present asnormal on physical examination and endocrine testing. There is some evidence that aberrantmetabolism of micronutrients such as choline may play a causative role in male factorinfertility. Choline is a crucial factor in the regulation of sperm membrane structure andmotility, and this nutrient plays an i...
