The half-cell reduction potentials of these redox couples in aqueous solutions at neutral pH, , provide a window to understanding the thermodynamic and kinetic characteristics of this triad and their associated chemistry and biochemistry dramatically. of the quinone governs the reaction of semiquinone ...
A fractal analysis, which takes into account the effect of surface heterogeneity brought about by ligand immobilization on the reaction kinetics in surface... A Ramakrishnan,Y Tan,A Sadana - 《IEEE Sensors Journal》 被引量: 22发表: 2005年 Consequence of heterogeneity of active sites for reactivit...
In contrast, identical isotope effects of 1.6 to 2.0 were observed in both Vmax and Vmax/Km when this reaction was studied with a substrate in which only one of the two N-methyl groups was substituted with deuterium. Furthermore, both the intermolecular and intramolecular isotope effects were ...
The retention of recovered enzyme after successive reaction cycles with xylan confirmed the effective immobilization. The bound enzyme with lower specific activity clarified juice faster than the free enzyme due to its operational stability and reusability. Samples of pineapple juice showed relatively less...
Understanding the kinetics of a chemical reaction is one of the most fundamental aspects of chemistry. However, kinetics experiments are not easy to perform. In fact, in the educational environment, most teaching laboratory experiments are related to synthesis, qualitative and quantitative analysis and...
Results In this study, we have investigated the kinetic mechanism of recombinant human Icmt. In the reaction catalyzed by Icmt, S-adenosyl-L-methionine (AdoMet) provides the methyl group that is transferred to the second substrate, the C-terminal isoprenylated cysteine residue of a CaaX protein,...
in such secretomes could provide some insight into the relevance of the H2O2-driven LPMO reaction and the flow of H2O2through different enzyme reactions. In this regard, one must bear in mind that the use ofkcat/\({K_{{\rm{mH}}_2{\rm{O}}_2}}\)values as performance metrics in ...
In the presence of PhIO as the oxidant, no reaction was observed for either chiral Fe(salen) C1 or Co(salen) C2 (entry 1). Chiral Mn(salen) C3 exhibited good oxidation catalysis reactivity, though poor chiral recognition was obtained (entry 2). Oxidation proceeded with excellent site ...
In subject area:Biochemistry, Genetics and Molecular Biology The kinetic isotope effect describes the slow-down of a chemical reaction when an atom in one of the reactants is replaced by one of its heavier isotopes. From:Trends in Molecular Medicine,2020 ...
