1. 6. Lipase Specificity and Selectivity : Engineering, Kinetics and Applied Catalysis

   Författare :Mohamad Takwa; Karl Hult; Bernhard Hauer; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

   Sammanfattning : The specificity and selectivity of the enzyme Candida antarctica lipase B (CALB) were studiedfor several substrates and applications.With help of molecular modeling, the active site of CALB was redesigned for the ring openingpolymerization of D,D‐lactide. LÄS MER

3. 7. Contributions to the understanding of diversity and evolution in the genus Coreomyces

   Författare :Henrik Sundberg; Stefan Ekman; Åsa Kruys; Donald H. Pfister; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ascomycetes; Coreomyces; Corixidae. DNA; DNA extraction; Fungi; ge-nome; host specificity; Laboulbeniales; mating types; MAT-loci; meth-odology; NGS; parasite; position specificity; systematics; taxonomy; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

   Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER

4. 8. Reading a glycocode - mechanism and function of galectin-glycan interactions

   Författare :Emma Salomonsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; galectin; specificity; affinity; multivalency; fluorescence anisotropy; glycan array; serum glycoproteins; anginex;

   Sammanfattning : There is an intensive interest in characterising the structure and function of galectins, which is not surprising given their many important cellular functions and strong implications in human disease. Understanding the mechanisms involved in galectin functions will help to find selective and novel strategies for disease treatment and diagnosis. LÄS MER

5. 9. Enzyme substrate solvent interactions : a case study on serine hydrolases

   Författare :Linda Fransson; Karl Hult; Jürgen Pleiss; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipase; esterase; specificity; Bioengineering; Bioteknik;

   Sammanfattning : Reaction rates and selectivities were measured for transacylation of fatty acid esters in solvents catalysed by Candida antarctica lipase B and by cutinase from Humicola insolens. With these enzymes classical water-based enzymology can be expanded to many different solvents allowing large variations in interaction energies between the enzymes, the substrates and the surrounding.

7. 10. Exploiting enzyme promiscuity for rational design

   Författare :Cecilia Branneby; Karl Hult; Alex Zaks; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Candida antarctica lipase B; alanine racemase; substrate specificity; reaction specificity; enzyme catalytic promiscuity; Biokemi; Biochemistry; Biokemi;

   Sammanfattning : Enzymes are today well recognized in various industrial applications, being an important component in detergents, and catalysts in the production of agrochemicals, foods, pharmaceuticals, and fine chemicals. Their large use is mainly due to their high selectivity and environmental advantage, compared to traditional catalysts. LÄS MER
