  1. 1. Human salivary esterases : a biochemical study of carboxylesterase and thio-esterase in human saliva with special reference to their inhibition by dental materials

    Författare :Lennart Lindqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Electrophoretic and gel chromatographic techniques have been developed in order to obtain partially purified esterases from small amounts of human saliva. These techniques permit the characterization of salivary esterase regarding substrate and inhibitor specificities, and lectin binding ability. LÄS MER

  3. 2. Studies on blood esterases : purification and characterization of a butyrylesterase from human erythrocytes

    Författare :Benny Axenfors; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The object of these studies has been blood esterasesi and especially a butyrylesterase present in human erythrocytes. First, thiophenyl esters were synthesized for use as substrates in assaying arylesterases according to the ElIman procedure. LÄS MER

  4. 3. Immobilization of feruloyl esterases in mesoporous silica

    Författare :Christian Thörn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mesoporous materials; Feruloyl esterases; Protein modeling; Biocatalysis; QCM-D; Hydroxycinnamic acids; Enzyme immobilization; Silica;

    Sammanfattning : Feruloyl esterases are a class of enzymes that can be used as biocatalysts for the modification of bioactive hydroxycinnamic acids. In industry, enzyme immobilization is often necessary to stabilize the enzymes and to allow their reuse. LÄS MER

  5. 4. Towards Classification and Functional Description of Enzymes: A case study of feruloyl esterases

    Författare :Gupta Udatha; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; descriptors; enzyme immobilization; catalytic triad; pharmacophore; enzyme promiscuity; functional classification; molecular docking; feruloyl esterases; protein evolution; structure-function relationship;

    Sammanfattning : The prediction of enzyme functionality from sequence or structure data remains a challenging task that can be best addressed by studying the structure-function relationships determined from previously available information. This thesis work was focused on developing a reliable classification and functional description for the feruloyl esterase (FAE) enzyme family, whose members’ possess both structural and catalytic promiscuity.

  7. 5. Feruloyl esterases - Evaluation of their potential for biotechnological applications

    Författare :Cyrielle Bonzom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-domain enzyme; acetyl esterase; enzyme immobilization; N-glycosylation; carbohydrate active enzyme family 1; acetyl xylan esterase; heterologous production; polysaccharide utilization loci; enzyme stability; feruloyl esterase;

    Sammanfattning : Owing to the current efforts to find sustainable alternatives to petrochemical based industries and technologies, enzymatic degradation and valorization of plant biomass has been attracting interest. Due to the complexity of plant biomass, an array of enzymes is required to hydrolyze it, including esterases. LÄS MER
