oxidoreductase or ox·i·do-re·duc·tase [ ok-si-doh-ri-duhk-teys, -teyz ]show ipanounBiochemistry. any of a class of enzymes that act as a catalyst, some of them conjointly, causing the oxidation and reduction of compounds.
At the same time, ‘synthase’ would be used for the synthesis-catalyzing enzymes that may or may not involve energy utilization. There are six classes of enzymes and ligases are one of them. The other classes of enzymes include oxidoreductases, transferases, hydrolases, isomerases, and lyases...
Examples of enzymes consisting of apoenzymes and coenzymes are transferases, oxidoreductases, ligases, and isomerases. Apoenzyme in DNA polymerase Apoenzymes are essential for a holoenzyme to function properly. One of the most important holoenzymes is DNA polymerase which is composed of a cofactor ...
Retinoid oxidoreductase catalyzing the synthesis of chromophores in photoreceptors in vision. Enzyme Complexity, Enzyme Specialization, and Enzyme Complications Complexity refers to an increase in difficulty arising in a technical system having multiple interdependent components. Highly complex enzymes have evolve...
In vivo/in vitro suppression by cytokines was congruent for some cytochrome P450 isoforms (Cyp1a2, Cyp2c29, and Cyp3a11) but not for others (cytochrome P450 oxidoreductase (POR) and Cyp2e1). Anomalously in a pilot study, commercial murine IL-6 and IL-6 receptor antibodies did not lower ...
Four protein complexes are involved in the electron transport chain. Complex I or NADH-ubiquinone oxidoreductase transfers electrons from NADH to Coenzyme Q (ubiquinone). Complex II or succinate dehydrogenase receives FADH2which is also found in the Krebs cycle. FADH2 transfers its electrons to ir...
Cytochrome P450 oxidoreductase deficiency (PORD) Cytochrome P450s reductase is a membrane-bound enzyme found in the smooth endoplasmic reticulum. This is a rare disorder caused by the deficiency of the enzyme Cytochrome P450s reductase. This disorder affects steroid hormones, which are essential for ...
(i.e. large cocci with a membrane system randomly arranged in tubes). They derive their energy through the oxidation of inorganic nitrogen compounds. They have complex internal membrane systems where enzymes such as ammonia monooxygenase (oxidizes ammonia to hydroxylamine) and nitrite oxidoreductase (...
