  1. 1. Assembly and Function of Nitric Oxide Reductase from Paracoccus denitrificans

    Författare :Maximilian Kahle; Pia Ädelroth; Hans-Georg Koch; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-heme iron; cofactor; heme-copper oxidase; AAA ; cNOR; chaperone; metal ion insertion; MoxR; nor accessory genes; FeB; liposomes; membrane mimetics; nanodiscs; reconstitution; enzymatic mechanism; NO reduction; O2 reduction; Biochemistry; biokemi;

    Sammanfattning : Bacterial denitrification is a part of the global nitrogen cycle and comprises the stepwise reduction of nitrate to molecular nitrogen, which is released to the atmosphere. Cytochrome c-dependent nitric oxide reductase (cNOR) from Paracoccus (P.) denitrificans catalyzes the reduction of nitric oxide to nitrous oxide and water. LÄS MER

  3. 2. Insight into 5-lipoxygenase biocatalysis and interaction with membrane components

    Författare :Ramakrishnan B Kumar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inflammation is one of the innate defence mechanisms exerted by the human body for protection and to initiate the healing process. Chronic inflammatory reactions can lead to several disease conditions like asthma, allergic rhinitis and rheumatoid arthritis. LÄS MER

  4. 3. Structural studies of HDL and applications of EM on membrane proteins

    Författare :Lin Zhu; Hans Hebert; Caroline Jegerschöld; Catherine Vénien-Bryan; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high density lipoprotein; rHDL; apoA-I; transmission electron microscopy; membrane protein; nanodisc; Salipro; transporter; Technology and Health; Teknik och hälsa;

    Sammanfattning : A large number of proteins interact with biological membranes, either integrated in the membrane (PepTSo2), embedded on a membrane surface (5-lipoxygenase) or encircling a cutout of lipid bilayer (apolipoprotein1 (apoA-I). They function as transporters, receptors or biocatalysts in cellular processes like inflammation or cholesterol transport which are touched upon here. LÄS MER

  5. 4. Membrane effects on proton transfer in cytochrome c oxidase

    Författare :Linda Näsvik Öjemyr; Peter Brzezinski; Anthony G. Lee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytochrom c oxidase; lipids; membrane; proton transfer; Biochemistry; biokemi;

    Sammanfattning : The biological membrane is composed of lipids and proteins that make up dynamic barriers around cells and organelles. Membrane-spanning proteins are involved in many key processes in the cell such as energy conversion, nerve conduction and signal transduction. LÄS MER

  7. 5. Nanostructured carbon materials prepared by hole-mask colloidal lithography

    Författare :Hans Fredriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HOPG; GC; Colloidal Lithography; Oxygen; RIE; Nanofabrication;

    Sammanfattning : Research and development of nanofabrication methods can be motivated both formanufacturing of commercially available products like micro electronic componentsand for development of model systems for fundamental and applied science. Thefabrication process developed during this work, hole-mask colloidal lithography(HCL), is primarily oriented towards the latter two, specifically for research in thefields of catalysis, nanoparticle plasmons, and bio- and fundamental physics.
