  1. 21. Mannan-hydrolysis by hemicellulases: enzyme-polysaccharide interaction of a modular beta-mannanase

    Författare :Per Hägglund; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biochemistry; hemicellulase; beta-mannanase; carbohydrate-binding modules; Biokemi; metabolism;

    Sammanfattning : The enzymatic degradation of plant polysaccharides is a process of fundamental importance in nature which involves a wide range of enzymes. In this work, the structure and function of hemicellulose-degrading enzymes was investigated. The focus was on a beta-mannanase (TrMan5A) produced by the filamentous fungus Trichoderma reesei.

  3. 22. Modeling of enzyme kinetics on polymeric substrates by simulation : Enzymatic hydrolysis of cellulose

    Författare :Veljo Sild; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Biopolymers are an essential constituent of living matter. To develop new products and processes based on enzyme production and modification and hydrolysis of biopolymers, enzymes with well understood mechanism are required. It is impossible to derive a universal analytical model for every particular enzyme/polymer system. LÄS MER

  4. 23. β-Mannoside hydrolases from clan A – Structural enzymology, subsite engineering and transglycosylation

    Författare :Anna Rosengren; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-mannosidase; β-mannanase; enzymology; kinetics; MALDI-TOF MS; protein engineering; protein structure; subsite organisation; transglycosylation;

    Sammanfattning : β-Mannoside hydrolases are enzymes that are involved in conversion of the major soft-wood hemicellulose O-acetyl-galactoglucomannan, an important renewable biomass resource. They belong to clan A of glycoside hydrolases and share a common (β/α)8-TIM barrel fold. LÄS MER

  5. 24. Selective extraction systems for detection and purification of membrane proteins

    Författare :Ulf Sivars; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; partitioning; Aqueous two-phase systems; separation; membrane proteins; detergent; micelle; polymer; Biochemistry; affinity; Metabolism; Biokemi;

    Sammanfattning : Increased understanding of membrane proteins is important for characterization of biochemical processes. Improved membrane protein isolation methods is a key issue for effective functional and structural determination of the large amount of unknown membrane proteins. LÄS MER

  7. 25. Enzymatic conversion of β-mannans through transglycosylation and hydrolysis : Synthesis of building blocks for novel biomaterials from renewables

    Författare :Samuel Butler; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-Mannanase; Transglycosylation; Enzymatic synthesis; Glycoconjugates; Enzyme synergy; α- Galactosidase; Galactoglucomannan; Enzyme engineering; MALDI-ToF MS; HPLC;

    Sammanfattning : The major softwood hemicellulose is galactoglucomannan (GGM), an abundant polysaccharide which constitutes up to 25% of the dry weight of wood, much of which is discarded in current refinery practices. Among the enzymes responsible for the degradation of this hemicellulose are the β-mannanases. LÄS MER
