  1. 16. Catalysis and Site-Specific Modification of Glutathione Transferases Enabled by Rational Design

    Författare :Sofia Håkansson Hederos; Lars Baltzer; Kerstin Broo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalysis; Glutathione Transferases; Rational design; Protein design; Site-specific modification; thiolester hydrolysis; Enzyme engineering; Enzymteknik;

    Sammanfattning : This thesis describes the rational design of a novel enzyme, a thiolester hydrolase, derived from human glutathione transferase (GST) A1-1 by the introduction of a single histidine residue. The first section of the thesis describes the design and the determination of the reaction mechanism. LÄS MER

  3. 17. Structure-Function Relationships of Pi Class Glutathione Transferase Studied by Protein Engineering

    Författare :Usama M. Hegazy; Bengt Mannervik; Mikael Widersten; T. J. Mantle; Uppsala universitet; []
    Nyckelord :Biochemistry; Glutathione transferase; targeted chemical modification; lock-and-key motif; cooperativity; stucture-function relationship; protein engineering; unnatural amino acid; site-specific mutation; Biokemi;

    Sammanfattning : The glutathione transferases (GSTs) represent a superfamily of dimeric proteins involved in cellular detoxication by catalyzing the nucleophilic addition of the reduced glutathione (GSH) to the hydrophobic electrophiles. The present work focuses on the functional role of the conserved structures of GSTP1-1. LÄS MER

    Sammanfattning : Bioinformatics is an emerging interdisciplinary research field in which mathematics. computer science and biology meet. In this thesis. bioinformatic methods for analysis of functional and structural properties among proteins will be presented. LÄS MER

  5. 19. Studies of calcium binding proteins 1 and 2 and protein kinase CK2

    Författare :Inger Janson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; calcium binding protein 1; calcium binding protein 2; calcium binding protein 4; erd2receptor; protein kinase CK2; endoplasmic reticulum; Golgi; microsomes; heparin; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

    Sammanfattning : The endoplasmic reticulum (ER) is a major intracellular compartment of eukaryotic cells and is the site of the synthesis and post-translational modification of both secretory and membrane glycoproteins. Upon cell rupture vesicles of several kinds are formed from cell membranes, mainly derived from ER and are called microsomes. LÄS MER

  7. 20. Purine and Pyrazolopyrimidine Derivatives: Design and Synthesis of Chemical Tools for Biological Applications

    Författare :David Bliman; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; purine; pyrazolopyrimidine; caged compounds; protein kinases; protein-protein interactions; fluorescence; organic synthesis;

    Sammanfattning : Purines can be found in a multitude of naturally occurring compounds with a range of functions. This thesis describes the design and synthesis of purines and structurally related pyrazolopyrimidine derivatives intended for biological applications. LÄS MER
