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

    Author : Ingrid Albertsson; Pia Ädelroth; Alessandro Giuffrè; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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). READ MORE

  2. 2. Genes for cytochrome c and cytochrome c oxidase synthesis in Bacillus subtilis

    Author : Jenny Bengtsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; cytochrome; cytochrome c oxidase; Bacillus subtilis; cytochrome c synthesis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Cytochromes are heme-containing proteins that function in electron transfer reactions, e.g. respiration and photosynthesis. There are several different types of cytochromes. READ MORE

  3. 3. Proton pathways in energy conversion : K-pathway analogs in O2- and NO-reductases

    Author : Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; Biochemistry; biokemi;

    Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

  4. 4. c Cytochromes as Electron Carriers in Microbial Chlorate Respiration

    Author : Anna Smedja Bäcklund; Thomas Nilsson; Pia Ädelroth; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; c cytochrome; chlorate reduction; electron transport; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : Microbial respiration of oxochlorates is important for the biotreatment of effluents from industries where oxochlorates are produced or handled. Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. READ MORE

  5. 5. Enzymes and electron transport in microbial chlorate respiration

    Author : Jan Bohlin; Thomas Nilsson; Lars-Gunnar Franzén; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Ideonella dechloratans; c cytochromes; chlorate; chlorate reductase; chlorite dismutase; heterologous expression; heme reconstitution; electron transport; oxidoreductas; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Microbial chlorate respiration plays an important role in the turnover of oxochlorates in nature and industrial waste management. This thesis deals with the characterization of the molecular components of chlorate respiration in Ideonella dechloratans. READ MORE
