  3. 17. Deciphering the Mechanistic Diversity of Proton-Coupled Electron Transfer Reactions

    Författare :Robin Tyburski; Leif Hammarström; Thomas Moore; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCET; Proton Coupled Electron Transfer;

    Sammanfattning : Proton coupled electron transfer is ubiquitous in biological and artificial reaction systems. Much has been done in order to describe the occurrence of such reactions. However, PCET reactivity is often very complex. For instance, there are multiple (stepwise and concerted) mechanistic pathways through which PCET may occur. LÄS MER

  4. 18. Molecular machinery of a membrane-bound proton pump : Studies of charge transfer reactions in cytochrome c oxidase

    Författare :Emelie Svahn; Peter Brzezinski; Ville Kaila; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane protein; respiration; redox reaction; cytochrome aa3; cytochrome c oxidase; Biochemistry; biokemi;

    Sammanfattning : In cellular respiration, electron transfer from the breakdown of foodstuff is coupled to the formation of an electrochemical proton gradient. This is accomplished through proton translocation by respiratory complexes, and the proton gradient is subsequently used e.g. to drive ATP production. LÄS MER

  5. 19. Proton-Conducting Sulfonated and Phosphonated Polymers and Fuel Cell Membranes by Chemical Modification of Polysulfones

    Författare :Benoit Lafitte; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Macromolecular chemistry; Makromolekylär kemi; Material technology; Materiallära; materialteknik; chemical modification; lithiation; fuel cells; polyelectrolyte; sulfonated polymers; proton-conducting polymer membranes polysulfone; phosphonated polymers;

    Sammanfattning : The proton exchange membrane fuel cell (PEMFC) is currently emerging as an efficient and environmentally friendly power source. The technology is very complex and relies ultimately on materials and components which need further development. LÄS MER

  7. 20. Energy Transduction and Sensory Signalling in Haloarchaea Structural Characterisation of the Photocycles of Bacteriorhodopsin and Sensory Rhodopsin II

    Författare :Karl Edman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinetic crystallography; proton pumping; Haloarchaea; structural mechanism; bacteriorhodopsin; sensory signalling; sensory rhodopsinII; retinal proteins;

    Sammanfattning : Archaeal rhodopsins belong a subfamily of heptahelical transmembrane proteins. All contain a buried retinal chromophore covalently bound to a conserved lysine residue in helix G via a protonated Schiff base. LÄS MER
