Abstract
In recent years there has been growing interest in methods for the degradation of polycyclic aromatic hydrocarbons. Cytochrome c (Cyt c) systems in the presence of H2O2 are able to oxidize various aromatic compounds. In order to investigate ways of improving the performance of Cyt c/H2O2 oxidation systems, site-directed mutagenesis, and chemical modifications on the hemoprotein surface with poly(ethylene glycol) and methylation of the active site have been performed. The EPR technique and UV-VIS spectroscopy have been used to identify radical intermediates and heme iron spin states of the chemical modified Cyt c (PEG-Cyt-Met) and Cyt c mutants.
