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

    Författare :Ingrid Albertsson; Pia Ädelroth; Alessandro Giuffrè; Stockholms universitet; []
    Nyckelord :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; biokemi; Biochemistry;

    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

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

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

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

    Författare :Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; Stockholms universitet; []

    Sammanfattning : 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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Jan Bohlin; Thomas Nilsson; Lars-Gunnar Franzén; Karlstads universitet; []
