TY - T1 - Comparison Between O and OH Intermediates of Cytochrome c Oxidase Studied by FTIR Spectroscopy SN - / UR - http://hdl.handle.net/10138/316050 T3 - A1 - Gorbikova, Elena; Kalendar, Ruslan A2 - PB - Y1 - 2020 LA - eng AB - Cytochrome c oxidase is terminal enzyme in the respiratory chain of mitochondria and many aerobic bacteria. It catalyzes reduction of oxygen to water. During its catalysis, CcO proceeds through several quite stable intermediates (R, A, PR/M, O/OH, E/EH). This work is concentrated on the elucidation of the differences between structures of oxidized intermediates O and OH in different CcO variants and at different pH values. Oxidized intermediates of wild type and mutated CcO from Paracoccus denit...
