The reactivity of alcohol dehydrogenase IIG (ADH IIG) from Pseudomonas putida HK5 with new heterocycle-pentacyanoferrate(III) complexes and hexacyanoferrate(III) was determined at pH 7.2. The pentacyanoferrate(III) complexes contained imidazole, pyrazole, pyridine, their derivatives and 2-aminobenzothiazole as the sixth ligand. The largest reactivity of the(More)
Complexes of pentacyanoferrate(III) and biologically relevant ligands, such as pyridine, pyrazole, imidazole, histidine, and other aza- and thia-heterocycles, were synthesized. Their spectral, electrochemical properties, electron exchange constants, electronic structure parameters, and reactivity with glucose oxidase from Aspergillus niger were determined.(More)
The modelling of molecule-molecule interactions has been widely accepted as a tool for drug discovery and development studies. However, this powerful technique is unappreciated in physiological and biochemical studies, where it could be extremely useful for understanding the mechanisms of action of various compounds in cases when experimental data are(More)
Previous kinetic investigations of fungal-peroxidase catalyzed oxidation of N-aryl hydroxamic acids (AHAs) and N-aryl-N- hydroxy urethanes (AHUs) revealed that the rate of reaction was independent of the formal redox potential of substrates. Moreover, the oxidation rate was 3–5 orders of magnitude less than for oxidation of physiological phenol substrates,(More)
Steady-state and single-turnover kinetics for the oxidation of the N-substituted phenothiazines (PTs) and phenoxazines (POs) catalyzed by fungal Coprinus cinereus peroxidase and Polyporus pinsitus laccase were investigated at pH 4–10. In the case of peroxidase, an apparent bimolecular rate constant (expressed as k cat/K m) varied from 1×107M−1s−1to(More)
Molecular modeling techniques were applied to study oligomeric derivatives of phenols, which are produced during peroxidase-catalyzed oxidation. The interaction of substrates and oligomers with Arthromyces ramosus peroxidase (ARP) was analyzed by docking and molecular dynamics methods. The most possible interaction site of oligomers is the active center of(More)
Ab initio quantum chemical calculations have been applied to the study of the molecular structure of phenol derivatives and oligomers produced during peroxidase-catalyzed oxidation. The interaction of substrates and oligomers with Arthromyces ramosus peroxidase was analyzed by docking methods. The most possible interaction site of oligomers is an active(More)
