Oxidation-reduction reactions of metal ions.
Several metal or metalloid ions exist in multiple oxidation states and can undergo electron transfer reactions that are important in biological and environmental systems. There are endogenous metal ions such as iron, copper, and cobalt that participate in oxidation-reduction reactions with species of oxygen like molecular dioxygen, superoxide, and hydrogen peroxide. These reactions may be modul...
متن کاملOxidation reactions by prostaglandin cyclooxygenase-hydroperoxidase.
oxidations of organic sulfides, amines, and even enzymes catalyzed by purified and microsomal forms of prostaglandin cyclooxygenase-hydroperoxidase have been studied using O2 incorporation into arachidonic acid to monitor oxygenase and [14C]15-hydroperoxyprostaglandin E2 reduction to prostaglandin E2 to measure hydroperoxidase. The oxygenase was protected by phenol against the irreversible deac...
متن کاملProbing enzyme-mediated oxidation reactions in crystallo*
Reaction intermediates define the chemical steps of transformation from substrates to products, and capture of intermediates along catalytic pathways remains one focal point in the studies of enzymatic mechanisms. Performing enzymatic reactions in protein single crystals has been shown to be very effective in trapping and identifying unstable intermediates. In this critical review, we provide s...
متن کاملNeocarzinostatin-based hybrid biocatalysts for oxidation reactions.
An anionic iron(III)-porphyrin-testosterone conjugate 1-Fe has been synthesized and fully characterized. It has been further associated with a neocarzinostatin variant, NCS-3.24, to generate a new artificial metalloenzyme following the so-called 'Trojan Horse' strategy. This new 1-Fe-NCS-3.24 biocatalyst showed an interesting catalytic activity as it was found able to catalyze the chemoselectiv...
متن کاملSpecial Issue: "Organic Reactions in Green Solvents".
To overcome the well-established drawbacks of conventional organic solvents (toxicity, non-biodegradability, flammability, accumulation in the atmosphere) remarkable research efforts have been recently devoted to the replacement of traditional organic reaction media by the so-called Green Solvents. In this sense, the choice of a safe, non-toxic, biorenewable and cheap reaction media is a crucia...
