  1. 6. Heme-copper oxidases and nitric oxide : Reaction mechanisms and supercomplex formation

    Författare :Ingrid Albertsson; Pia Ädelroth; Alessandro Giuffrè; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heme-copper oxidase; nitrite reductase; nitric oxide reductase; nitric oxide; supercomplex; Paracoccus denitrificans; denitrification pathway; proton transfer pathway; C-type oxidase; Helicobacter pylori; Biochemistry; biokemi;

    Sammanfattning : In the denitrification process where nitrate is stepwise reduced to nitrogen gas, the toxic molecule nitric oxide (NO) is formed as an intermediate. Nitric oxide is produced by the enzyme cd1 Nitrite reductase (cd1NiR) by reduction of nitrite and is later reduced to nitrous oxide by nitric oxide reductase (cNOR). LÄS MER

  3. 7. Bacterial Terminal Oxidases. Studies in Bacillus subtilis

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

    Sammanfattning : 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. LÄS MER

  4. 8. Transmembrane proton transfer in biological systems : an investigation of bacterial and archaeal haem-copper oxidases

    Författare :Gwen Gilderson; Ólöf Einarsdóttir; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Haem-copper oxidases are membrane-bound protein complexes that catalyse the reduction of dioxygen to water in the respiratory chain. These enzyme complexes are molecular machines that couple the free energy released from this reaction to pump protons across the membrane. LÄS MER

  5. 9. Kinetics of proton and electron transfer in heme-copper oxidases

    Författare :Peter Lachmann; Pia Ädelroth; Örjan Hansson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heme-copper oxidase; electron transfer; proton transfer; nitric oxide reductase; ba3 oxidase; flow-flash; laser-flash photolysis; Biochemistry; biokemi;

    Sammanfattning : Heme-copper oxidases are transmembrane proteins that are found in aerobic and anaerobic respiratory chains. During aerobic respiration, these enzymes reduce dioxygen to water. The energy released in the reaction is used to transport protons across a biological membrane. LÄS MER

  7. 10. Semicarbazide-sensitive Amine Oxidase (SSAO) – Regulation and Involvement in Blood Vessel Damage with Special Regard to Diabetes : A Study on Mice Overexpressing Human SSAO

    Författare :Camilla Göktürk; Lars Oreland; Karin Forsberg-Nilsson; Dan Larhammar; Peter Yu; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; amine oxidases; VAP-1; vascular complications; diabetes; blood pressure; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Sammanfattning : Semicarbazide-sensitive amine oxidase (SSAO, EC 1.4.3.6) belongs to a family of copper-containing amine oxidases. LÄS MER
