Catalytic importance of acidic amino acids on subunit NuoB of the Escherichia coli NADH:ubiquinone oxidoreductase (complex I).

The Journal of biological chemistry - 25 Aug 2006

Abstract excerpt

The NADH:ubiquinone oxidoreductase (complex I) from Escherichia coli is composed of 13 subunits called NuoA through NuoN and contains one FMN and 9 iron-sulfur clusters as redox groups. Electron transfer from NADH to ubiquinone is coupled with the translocation of protons across the membrane by a yet unknown mechanism. Redox-induced Fourier transform infrared difference spectroscopy showed that the oxidation of...
