Electron cryomicroscopy structures of respiratory supercomplexes from alphaproteobacteria suggest mechanisms to enhance catalysis and to prevent deactivation of respiratory complex I
… the concentration of hydrophobic substrate ubiquinone-10 between the reaction centres. A physical tether anchors the membrane tethered cytochrome c552 not only at the CIII-CIV interface, but also to cytochrome c1, the electron donor site, explaining why cytochrome c552 can function as an …

Characterizations on bacterial photosynthesis and respiration with optical spectroscopy and magnetic resonance
… HA- (bacteriopheophytin in the A branch) to QA (ubiquinone in the A branch) and back electron transfer from QA- to P+ (special pair of bacteriochlorophyll). Both electron transfers slows down by about 4 fold at room temperature. I have also examined the reactivity of the semiquinones in the LM …

Cryo-EM studies of substrate and inhibitor binding to mammalian respiratory complex I
Mammalian respiratory complex I (NADH:ubiquinone oxidoreductase) is an intricate multi-subunit, energy-transducing membrane protein that is essential for aerobic energy metabolism and NADH/NAD⁺ homeostasis. It couples the energy released from NADH oxidation and ubiquinone (Q) reduction to pump four …
