1. 1. Rational engineering of esterases for improved amidase specificity in amide synthesis and hydrolysis

   Författare :Peter Hendil-Forssell; Mats Martinelle; Romas J. Kazlauskas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amidase; Biocatalysis; Enzyme; Esterase; Enzyme engineering; Lipase; Substrate specificity; Bioteknologi; Biotechnology;

   Sammanfattning : Biocatalysis is an ever evolving field that uses enzymes or microorganisms for chemical synthesis. By utilizing enzymes that generally have evolved for specific reactions under mild conditions and temperatures, biocatalysis can be a more environmentally friendly option compared to traditional chemistry.

3. 2. 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. 3. The Importance of Being Promiscuous : Understanding enzyme function, specificity, and evolution through structure

   Författare :Annika Söderholm; Maria Selmer; Birte Höcker; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Enzyme evolution; enzyme promiscuity; X-ray crystallography.;

   Sammanfattning : Enzymes are known to be amazingly specific and efficient catalysts. However, many enzymes also have so-called promiscuous functions, i.e., they are able to catalyze other reactions than their main one. LÄS MER

5. 4. 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

7. 5. Combinatorial protein engineering applied to enzyme catalysis and molecular recognition

   Författare :Malin Eklund; KTH; []
   Nyckelord :phage display; selection; enzyme; affinity domains; crystal structure; affibody; lipase; protein engineering; protein A; assembly;

   Sammanfattning : The recent development of methods for constructing andhandling large collections (libraries) of proteins, from whichvariants with desired traits can be isolated, hasrevolutionized the field of protein engineering. Key elementsof such methods are the various ways in which the genotypes(the genes) and the phenotypes (the encoded proteins) arephysically linked during the process. LÄS MER
