The reactions of superoxide ion, O − 2, with some non-redox metalloporphyrins were investigated at room temperature by spectroscopic methods (UV/vis, ESR) in dimethyl sulfoxide (DMSO). Addition of the O − 2 solutions prepared from KO 2 to DMSO solutions of the meso-tetraphenylporphyrin ...
other mechanisms, involving formation of hydrogen peroxide under physiological conditions, have been proposed. Redox-inert zinc (Zn) is the most abundant metal
The non-redox and redox systems will be considered separately. Examples are selected carefully, to cover the widest possible range of diversity of systems under consideration. The elemental, core and concentration balances will be Equilibrium versus metastable systems The principle of the Generalized ...
Redox partner proteins of diheme cytochromes b are mainly iron-sulfur proteins or c-type cytochromes (Table 4; see also Figs 2 and 4 for examples). In many cases, electron transport catalyzed by diheme b-type cytochromes is coupled to the generation of a pmf across the membrane, either by...
In the second method, the efficiency was calculated by dividing the amount of energy required to result in the observed cell growth by the amount of light energy received in the P-chamber (see Supplementary Methods for examples for each method). Molecular microbiological techniques. Genomic DNA ...
However, several examples have shown that the window for target recognition can also be located upstream or downstream of ribosome-bind- ing site/AUG sequences (Vecerek et al., 2007; Bouvier et al., 2008; Desnoyers et al., 2009; Pfeiffer et al., 2009), and that some small RNA (sRNA...
1a)26. Whilst currently limited to the SidD NRPS, these examples of nonlinear behaviour begin to highlight the intricate and highly unusual molecular programming of fungal NRPSs. The biosynthesis of siderophores belonging to the ferrichrome family have been linked to an evolutionarily-related group ...
Fuel cells [1,2], catalyst materials [3–8], thermopower applications [9], capacitors [10], solar cells [11,12], and sensors [13–16] are some examples of these solutions. Especially, nanoparticles are used in a wide variety of applications [17–28]. Materials are also used corporate...
Besides, the slow electron transfer kinetics of hydrophobic analytes, such as tyrosine, can limit the redox reaction rate and deteriorate biosensor performance [37]. Bare electrodes perform poorly because other interfering species present can be oxidized non-selectively. Surface modification can catalyze ...
