  1. 1. Protein-protein interactions in model systems : design, control of catalytic activity and biosensor applications

    Författare :Johan Rydberg; Lars Baltzer; Joel Schneider; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein interactions; design; catalysis; biosensors; hybride materials; nanoparticles; Kemi; Chemistry; Kemi;

    Sammanfattning : This thesis describes the design of polypeptides, unordered in the monomeric state but capable of folding into helix-loop-helix motifs and dimerise to form four-helix bundles. The goal of the design was to encode them with the capacity to form dimers highly selectively and the ability to carry out molecular functions in the folded state but not in the unordered state, and thus to establish a molecular link between recognition and function.

  3. 2. Engineering carbonic anhydrase for highly selective ester hydrolysis

    Författare :Gunnar Höst; Bengt-Harald Jonsson; Lars-Göran Mårtensson; Per Berglund; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbonic anhydrase; specificity; hydrolysis; rational design; protein engineering; plasmodium falciparum; Bioengineering; Bioteknik;

    Sammanfattning : I denna avhandling presenteras arbete utfört med enzymet humant karboanhydras II (HCAII). Enzymer är en typ av proteiner som accelererar (katalyserar) kemiska reaktioner, vilket är nödvändigt för allt levande. Den naturliga funktionen för HCAII är att katalysera omvandlingen av gasen koldioxid till vätekarbonat, som är löslig i vätska. LÄS MER

  4. 3. Exploring the Wood Adhesive Performance of Wheat Gluten

    Författare :Petra Nordqvist; Eva Malmström Jonsson; Mats Johansson; Bo Mattiasson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plant protein; wood adhesive; mechanical properties; wheat gluten; soy protein isolate; gliadin; glutenin; adhesion; hydrolysis; heat treatment; AFM;

    Sammanfattning : The increasing environmental concern has reawakened an interest in materials based on renewable resources as replacement for petroleum-based materials. The main objective of this thesis was to explore plant proteins, more specifically wheat gluten, as a binder in wood adhesives intended for typical solid wood applications such as furniture and flooring.

  5. 4. Ribosomal Stalk Protein L12 : Structure, Function and Application

    Författare :Chandra Sekhar Mandava; Suparna Sanyal; Knud Nierhaus; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; protein synthesis; L12 dimer; initiation; elongation; G factors; and His-tag; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : Ribosomal stalk proteins are known to play important role in protein synthesis. The ‘stalk’, an extended structure on the large subunit of the ribosome is composed mainly of two to three dimers of L12 and one L10 protein, which forms the base of the stalk. In E. LÄS MER

  7. 5. Computational Protein Evolution : Modeling the Selectivity and Promiscuity of Engineered Enzymes

    Författare :Klaudia Szeler; Shina C. Lynn Kamerlin; Mikael Widersten; Maria Ramos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; enzymes; kinetics; catalysis; density functional theory; empirical valence bond; diesters; evolution; promiscuity; Biokemi; Biochemistry;

    Sammanfattning : Enzymes are biological catalysts that significantly increase the rate of all biochemical reactions that take place within cells and are essential to maintain life. Many questions regarding their function remain unknown. LÄS MER
