  1. 11. Amine Transaminases in Biocatalytic Amine Synthesis

    Författare :Henrik Land; Per Berglund; Helen C. Hailes; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amine Transaminase; Biocatalysis; Transamination; Reductive Amination; Enzyme; Enzyme Engineering; Equilibrium Displacement; Screening; Enzyme Stability; Bioteknologi; Biotechnology;

    Sammanfattning : The use of enzymes, nature´s own catalysts, both isolated or as whole cells to perform chemical transformations is called biocatalysis. As a complement to classical chemical catalysis, biocatalysis can be an environmentally friendly and more economical option in the production and synthesis of chemicals. LÄS MER

  3. 12. Metaproteogenomics-guided enzyme discovery : Targeted identification of novel proteases in microbial communities

    Författare :Mikaela Johansson; Martin Karlsson; Bengt-Harald Jonsson; Florian-Alexander Herbst; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Industrial biotechnology is a large and growing industry as it is part of establishing a “greener” and more sustainable bioeconomy-based society. Using enzymes as biocatalysts is a viable alternative to chemicals and energy intense industrial processes and is en route to a more sustainable industry. LÄS MER

  4. 13. Enzyme assays for lignin–carbohydrate bond hydrolysis

    Författare :Hampus Sunner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enzyme kinetic param- eter estimation; Glucuronoyl esterase; Enzyme assays; Lignin-carbohydrate bonds; Synergistic enzyme assay;

    Sammanfattning : To identify, produce, and use enzymes, analytical methods known as enzyme assays are employed. Enzyme assays are based on analysing the changes brought about on a substrate by an enzyme under defined conditions. Assays are often based on simplified reactions acting as substitutes for the reaction of interest. LÄS MER

  5. 14. On Catalytic Mechanisms for Rational Enzyme Design Strategies

    Författare :Charlotte Kürten; Per-Olof Syrén; Rudolf Allemann; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; catalytic mechanisms; terpene cyclase; triterpene cyclase; solvent dynamics; protein hydration; thermodynamics; quantum tunneling; polycyclization; natural compounds; ? ?-hydrolase; esterase; amidase; enzyme engineering; biocatalysis; Bioteknologi; Biotechnology;

    Sammanfattning : Enzymes enable life by promoting chemical reactions that govern the metabolism of all living organisms. As green catalysts, they have been extensively used in industry. However, to reach their full potential, engineering is often required, which can benefit from a detailed understanding of the underlying reaction mechanism. LÄS MER

  7. 15. Protein Engineering of Candida antarctica Lipase A : Enhancing Enzyme Properties by Evolutionary and Semi-Rational Methods

    Författare :Anders G. Sandström; Jan-Erling Bäckvall; Uwe T. Bornscheuer; Stockholms universitet; []
