  1. 1. Protein production, characterization and structure determination in structural genomics

    Författare :Esmeralda A. Woestenenk; Torleif Härd; Göran Karlsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; protein production; protein solubility; fusion tags; nuclear magnetic resonance; structure determination; Biologi; Biology; Biologi;

    Sammanfattning : This thesis covers the process from expression of a heterologous gene in Escherichia coli to structure determination of a protein by nuclear magnetic resonance (NMR) spectroscopy. The first part concerns structural genomics-related parallel screening studies on the effect of fusion tags (in particular the His tag) on protein solubility and the use of fusion tags in fast, parallel purification protocols intended for initial biophysical characterization of human proteins produced in E.

  2. 2. Physiology of Saccharomyces cerevisiae Producing Recombinant Insulin in Continuous Culture

    Författare :Ali Kazemi Seresht; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unfolded protein response; Keywords: heterologous protein production; prolonged chemostat; transcriptome; insulin analogue precursor; metabolic adaptation; URA3d; plasmid copy number; promoter truncation; high cell density cultivation; TPI1;

    Sammanfattning : The yeast Saccharomyces cerevisiae has widely been used as a host for the production of heterologous proteins. High-level production of heterologous proteins is likely to impose a metabolic burden on the host cell and can thus affect various aspects of cellular physiology. LÄS MER

  3. 3. Functional studies and engineering of family 1 carbohydrate-binding modules

    Författare :Janne Lehtiö; KTH; []
    Nyckelord :Cellulose-binding; carbohydrate-binding modules; phage display; bacterial surface display; combinatorial protein library; protein engineering; Trichoderma reesei; Staphylococcus carnosus;

    Sammanfattning : The family 1 cellulose-binding modules (CBM1) form a groupof small, stable carbohydrate-binding proteins. These modulesare essential for fungal cellulosedegradation. This thesisdescribes both functional studies of the CBM1s as well asprotein engineering of the modules for several objectives. LÄS MER

  4. 4. In vitro and in vivo approaches in the characterization of XTH gene products

    Författare :Nomchit Kaewthai; Harry Brumer; Jocelyn Rose; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabiodopsis thaliana; Hordeum vulgare; plant cell wall; xyloglucan; glycoside hydrolase family 16; xyloglucan endo-transglycosylase hydrolase gene family; xyloglucan endo-hydrolase; heterologous protein expression; Pichia pastoris; T-DNA insertion; in situ XET XEH assay; high-througput screening; Plant physiology; Växtfysiologi; Biochemistry; Biokemi; Functional genomics; Funktionsgenomik; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : ABSTRACT The xyloglucan endo-transglycosylase/hydrolase (XTH) genes are found in all vascular and some nonvascular plants. The XTH genes encode proteins which comprise a subfamily of glycoside hydrolase (GH) family 16 in the Carbohydrate-Active enZYmes (CAZY) classification. LÄS MER
