  1. 36. 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. 37. Oxidation of Ketones: A (Chemo-) Enzymatic Approach Using Oxygenases and Hydrolases

    Författare :Georgina Chávez; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cross linked enzyme aggregates.; caprolactone; perhydrolase; Lipase B from Candida antarctica;

    Sammanfattning : Oxidation reactions are important in organic chemistry as well as in nature. In industry, oxidations are commonly used for the synthesis of chemicals and pharmaceuticals, however such processes have a number of limitations, they use chlorinated solvents, stoichiometric oxidation reagents, and in some cases the reagents that have risks of explosion during transportation and storage.

  4. 38. Enzymatic synthesis of acrylates. Catalyst properties and development of process and product

    Författare :Mathias Nordblad; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; enzyme kinetics; process development; enzyme stability; enzyme immobilisation; acrylation; lipase;

    Sammanfattning : The increasingly apparent environmental problems in our surroundings necessitate a quest for sustainable development in all areas of human endeavour. Within the field of chemistry and the production of chemicals, the focus is increasingly on the development of green chemistry. LÄS MER

  5. 39. Novel chemical and enzymatic routes to the generation of heparin- related polysaccarides

    Författare :Jianhui Rong; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparin; heparan sulphate; biosynthesis; 2-O-sulphotransferase; neo-glycosaminoglycan; conjugation; Biokemi; Biochemistry; Biokemi; Medical Biochemistry; medicinsk biokemi;

    Sammanfattning : Heparin and heparan sulphate (HS) are structurally related polysaccharides influencing various biological processes. The biological functions of heparin/HS largely depend on interactions between the negatively charged polysaccharide chains and a variety of proteins. LÄS MER

  7. 40. Multiple Functions of Glutathione Transferases : A Study on Enzymatic Function, Regulatory Role and Distribution in Mouse and Man

    Författare :Maryam Edalat; Joseph De Pierre; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : To cope with various endogenous toxin and xenobiotics nature has equipped the organisms with a proper protection system. Glutathione transferases (GSTs) are important components of the cellular defense against oxidative stress. These proteins appear to be suited for different tasks. LÄS MER
