| dc.description.abstract | The oxidation of 1-pyrene butyric acid (PBA) as a model of polycyclic aromatic hydrocarbon catalyzed with recombinant Coprinus cinereiis peroxidase was studied at pH 4.0-7.5. The apparent bimolecular constant of PBA oxidation varied from 5.4 •103 to 7.3 •102 M-1s-1 at pH 4.0-7.0. The apparent pKa of reactivity change was 4.9 ±0.3. PBA oxidation at pH 4.0 proceeded in absence of extra-added hydrogen peroxide. The scheme of PBA oxidation at acid pH was suggested. | eng |
| dc.description.abstract | Tirta vieno iš policiklinių aromatinių junginių grupės atstovo - 1-pireno sviesto (butano) rūgšties (PBA) - oksidacija, katalizuojama rekombinantine Coprinus cinereus peroksidaze. pH intervale 4,0-7,5 PBA oksidacijos tariamoji bimolekulinė konstanta kito nuo 5,4 •103 M-1s-1 iki 7,3 •102M-1s-1. Tariamoji reaktyvumo pKa 4,9 ± 0,3. Nustatyta, kad PBA oksidacija, esant pH 4,0, vyksta be peroksido. Pasiūlyta PBA oksidacijos rūgštinėje terpeje schema. | lit |
