Insights into the structure and function of redox-active tyrosines from model compounds

Article Abstract:

A study of tyrosyl radicals in model compounds, generated by UV photolysis was carried out, which provided new information about the structure and functions of redox-active species. In cytochrome c oxidase, a cross-linked tyrosine-histidine cofactor was proposed to play a role in a proton and electron transfer reactions.

Interaction of NO with nanosized Ru-, Pd-, and Pt-doped SnO2: Electron paramagnetic resonance, Mossbauer, and electrical investigation

Article Abstract:

A study on the mechanism of NO interaction with nanosized Ru(Pd,Pt)-doped SnO2 is carried out by using electron paramagnetic resonance, Mossbauer, and electric resistance measurements. Details of the three steps that were proposed for the reaction between the semiconductor oxide and the gaseous component are discussed.
