  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. Development and Application ofEnzymatic Asymmetric Synthesis ofFunctionalized Alcohols

    Författare :Bin Yang; Jan-Erling Bäckvall; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The main focus of this thesis lies on enzymatic asymmetric organic reactions. In the first part ofthis work, we looked into the lipase-catalyzed transesterification and hydrolysis at the molecularlevel. LÄS MER

  4. 8. Design of enzymatic systems for the modification of cellulose fiber surfaces

    Författare :Malin Gustavsson; KTH; []
    Nyckelord :Candida antarctica lipase B; Pichia pastoris; cellulose-binding module; proteolysis; carbohydrate ester; xyloglucan endotransglycosylase; fiber modification;

    Sammanfattning : This thesis describes the design of enzymatic systems forthe modification of cellulose fiber surfaces. A single-enzymeapproach employed a conjugate between theNeocallimastix patriciarumCel6A cellulose-bindingmodule and lipase B fromCandida antarctica(CBM-CALB) to enhance theaccessibility of the enzyme to the target hydroxyl groups.

  5. 9. Lipase and ω-Transaminase : Biocatalytic Investigations

    Författare :Maria Svedendahl; Per Berglund; Stefan Stefan Lutz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Candida antarctica lipase B; enzyme catalysis; enzyme catalytic promiscuity; molecular modeling; ω-transaminase; Biochemistry; Biokemi;

    Sammanfattning : In a lipase investigation, Candida antarctica lipase B (CALB) are explored for enzyme catalytic promiscuity. Enzyme catalytic promiscuity is shown by enzymes catalyzing alternative catalytic transformations proceeding via different transition state structures than normal. LÄS MER

  7. 10. Exploring fatty acid derivatives from renewable resources as raw materials for coating applications

    Författare :Samer Nameer; Mats Johansson; Mats Martinelle; Dean Webster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epoxy; vegetable oils; birch bark; thermoset; bio-based; fatty acid; renewable resources; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : In the work presented herein, epoxy fatty acid derivatives were explored in the formation of thermosets for coating applications. The epoxy fatty acid derivatives were obtained from renewable resources such as birch tree bark and epoxidized linseed oil. LÄS MER
