  2. 21. Choreography of a proton pump : Studies of charge-transfer reactions in cytochrome c oxidase

    Author : Jóhanna Vilhjálmsdóttir; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; respiration; proton pump; electron transfer; proton transfer; proton-transfer pathway; midpoint potential; proton-pumping mechanism; Biochemistry; biokemi;

    Abstract : In the last step of cellular respiration, electrons from metabolites are transferred to molecular oxygen, mediated by the enzyme complexes of the respiratory chain. Some of these enzyme complexes couple these redox reactions to formation of an electrochemical proton gradient across the cell membrane. The proton gradient is used e.g. READ MORE

  4. 22. Paramagnetic states of diiron carboxylate proteins

    Author : Nina Voevodskaya; Astrid Gräslund; Peter Brzezinski; Howard Dalton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron paramagnetic resonance; diiron carboxilate proteins; ribonucleotide reductase; alternative oxidase; Biophysics; Biofysik;

    Abstract : Diiron carboxylate proteins constitute an important class of metall-containing enzymes. These proteins perform a multitude of reactions in biological systems that normally involve activation of molecular oxygen at the diiron site. READ MORE
