  2. 11. Bacterial Terminal Oxidases. Studies in Bacillus subtilis

    Author : Lena Winstedt; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mycology; virology; mykologi; bakteriologi; Mikrobiologi; bacteriology; Microbiology; di-copper center; cytochrome oxidase; Enterococcus faecalis; cytochrome bd; Bacillus subtilis; terminal oxidase; virologi;

    Abstract : The final step in aerobic respiratory pathways is catalyzed by terminal oxidases. Bacteria generally have two or more terminal oxidases. Aerobically grown Bacillus subtilis synthesize three terminal oxidases: one cytochrome c oxidase, cytochrome caa3 and two quinol oxidases, cytochrome aa3 and cytochrome bd. READ MORE

  4. 12. Structural studies on the integral membrane protein, ubiquinol oxidase from Escherichia coli

    Author : Jeff Abramson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; crystal structure; ubiquinol oxidase; membrane protein; oxidases; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Heme-copper oxidases are redox-driven proton pumps that couple the reduction of molecular oxygen to water with the vectorial translocation of protons across the membrane. The proton gradient generated by heme-copper oxidases and the other members of the aerobic respiratory chain is ultimately used to drive the synthesis of ATP. READ MORE

  5. 13. Redox Reactions of NO and O2 in Iron Enzymes : A Density Functional Theory Study

    Author : Mattias Blomberg; Per Siegbahn; Adrian Mulholland; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzyme catalysis; redox reactions; cytochrome oxidase; nitric oxide reductase; hyponitrous acid anhydride; peroxynitrite; myoglobin; prostaglandin synthase; PGHS; NO; N2O; O2; CO; Chemical physics; Kemisk fysik;

    Abstract : In the present thesis the density functional B3LYP has been used to study reactions of NO and O2 in redox active enzymes.Reduction of nitric oxide (NO) to nitrous oxide (N2O) is an important part in the bacterial energy conservation (denitrification). READ MORE
