Synthetic/artificial protein switches provide an efficient means of controlling protein functions using chemical signals and stimuli. Mutually exclusive proteins, in which only the host or guest domain can remain folded at a given time owing to conformational strain, have been used to engineer novel protein switches that can switch enzymatic functions on and off in response to ligand binding. T...
Cytochrome c was adsorbed readily and remained electroactive, with a redox potential of 32 mV, on TiO2 films placed on SnO2; similar behaviour was observed in glycerol, whereas in acetonitrile, irreversible oxidation occurred at a potential of 800 mV.
Oxidation (off state) and reduction (on state) of a single azurin molecule is monitored, one electron at a time, which depend on the chemical redox potential. By analysing the fluorescence time traces from individual azurin molecules, reaction kinetics and redox thermodynamics were determined.
The wide range of variability of the reduction potential (E(0)) of blue-copper proteins has been the subject of a large number of studies in the past several years. In particular, a series of azurin mutants have been recently rationally designed tuning E(0) over a very broad range (700 mV) without significantly altering the redox-active site [Marshall et al., Nature, 2009, 462, 113]. This clear...
It is no surprise that the catalytic activity of electron-transport enzymes may be optimised at certain electrochemical potentials in ways that are analogous to observations of pH-rate optima. This property is observed clearly in experiments in which an enzyme is adsorbed on an electrode surface which can supply or receive electrons rapidly and in a highly controlled manner. In such a way, the ...
The potential-energy surface for has been computed at the HF/6-311G** and MP2/6-311G** levels. The calculated H É 2 results conÐrm that trans-planar HOSO is a transition state but not a stable structure. The decomposition channel for the HOSO adduct has been studied by analysing the transition states and stationary points. The kinetic stimulus for the rearrangement and dissociation of the radic...
One of the greatest challenges of renewable resources is unpredictable nature of these resources. Nevertheless use of fossil-renewable integrated hybrid system, which uses some renewable resources rather than a single source, for the supply of power, is the most affordable and the most reliable method. In this study by use of analytical programming approach and 2012 base year statistics, produc...
