Geometry of the complexes between horse radish peroxidase and aromatic substrates was studied by means of new technique of precision measurement of NMR shifts. Weak dipolar shifts of hydroquinone and parametoxiphenole PMR in the presence of high spin peroxidase were recorded. Polar and azimuth angles in coordinate axes of peroxidase hem for the binding site(More)
The study of the flavin mononucleotide (FMN)-reduced nicotinamide adeninedinucleotide (NADH) reaction was carried out both under aerobic and anaerobic conditions, using spectrophotometric and titrimetric methods. The consumption of NADH was shown to exceed two times the consumption of FMN in the anaerobic reaction and the rate constant in the aerobic(More)
A modulation free Electron Spin Resonance spectrometer was used for the registration of spectral absorption lines of a spin-labeled Escherichia coli phenylalanine tRNA in solution with low (less than 0.1%) line shape distortion. The analysis of line shape of two different spin-labels introduced into position 8 revealed that phenylalanine tRNA in solution(More)
The reduction of flavin by reduced diphosphopyridine nucleotide and photoreduction were studied spectrophotometrically. Flavin was covalently bound to aminoethylcellulose, therefore the interaction between flavin molecules was excluded. Nevertheless a considerable quantity of free radicals was demonstrated under these conditions. The experimental dependence(More)
The kinetic parameters of p-aminohippurate transport and activity of the alkaline phosphatase were studied using brush-border membrane vesicles isolated from the kidney cortex of normal and mutant (strain of Campbell) rats. p-Aminohippurate (PAH) transport of both normal and mutant animals was carried out by the mechanism of facilitated diffusion. The(More)
