I. Dissociation and aromatization of a semibenzene. Reactions of triphenylmethyl and methyl isobutyryl radicals. II. The chemistry of alpha- and beta- azo radicals
… product of triphenylmethyl and methyl isobutyryl radicals (5), affords exactly these intermediates on thermolysis or, inefficiently, on direct photolysis. Whereas thiophenol or triplet 9-fluorenone aromatize 1, thermolysis in the presence of 1,4-cyclohexadiene allows trapping of 5 and oligomeric …

Mechanistic study and protein engineering of a dye-decolorizing peroxidase from Thermomonospora curvata for enhanced and expanded functions
… as a target for tuning substrate access and radical stability. Replacing E293 with glycine (E293G) enhanced peroxidase activity toward small-sized substrates, likely due to increased heme accessibility through an expanded substrate channel, as confirmed by our crystal structure. Surprisingly, …

Electrochemical oxidation of aliphatic carboxylates: Kinetics, thermodynamics, and evidence for a shift from a concerted to a stepwise mechanism in the presence of water
… the series which is expected trend based on radical stabilization energies of the alkyl groups on the aliphatic carboxylates. Hydrogen bonding was investigated as a possible source for the discrepancy between our results and the reported mechanism of the dissociative electron transfer. …

Biochemical characterization of a-type heme-copper oxidases in escherichia coli, bacillus subtilis and thermus thermophilus
… and Gln101) involved in ubiquinone semiquinone radical stabilization at quinone binding site in E. coli cytochrome bo3 oxidase. Similar result was reported on cytochrome aa3-600 oxidase in B. subtilis, a close homolog to cytochrome bo3 that uses menaquinone instead of ubiquinone. Recently, in …
