- Аннотация: The effect of gold on the cell components of bacteria Micrococcus luteus was studied ESR. The redox state of the membranes was assessed using two hydrophobic nitroxyl probes with the nitroxyl groups located in the middle and near the surface of the phospholipid bilayer. The redox state of the cytoplasm was studied using the endogenous lysodectose. The gold-containing membrane–protein complex was found to markedly decrease the amplitude of the ESR spectrum of lysodectose. Changes in the amplitude of ESR signals of the probes and lysodectose after the addition of colloid gold and various inhibitors of the electron transfer chain reflect the changes in the redox state of bacterial cells and the interrelations between chemical reactions in the membranes and cytoplasm. The analysis of results indicates that colloid gold shifts the electron flow toward the alternative oxidase o (cyt b558).
