  2. 1. Studies on mRNA turnover in bacteria

    Author : Martin Persson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; aprE; GlpP; glpD; mRNA secondary structure; Bacillus subtilis; mRNA stability; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Genetic information, which is stored in DNA, is transferred to messenger RNA (mRNA) in a process called transcription. mRNAs are then translated by ribosomes into proteins which, with some important exceptions, catalyze chemical reactions in cells. Since cells must be able to adapt to changes in the environment, mRNAs must be unstable. READ MORE

  4. 2. Vitreoscilla Haemoglobin. Genetic Fusions and Metabolic Characterisation

    Author : Viktoria Roos; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Metabolism; Biokemi; metabolism; osmotic stress; transcript profiling; DNA microarrays; random elongation mutagenesis; directed evolution; mRNA structure; Vitreoscilla haemoglobin VHb ; Escherichia coli; salt stress.;

    Abstract : Vitreoscilla is an obligate aerobic bacterium living in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla expresses a homodimeric haemoglobin (VHb) when subjected to oxygen-limited conditions. READ MORE

  5. 3. Structural and Functional Studies of Wilms Tumour Protein - WT1; Novel Insights into Functionality of Zinc Finger Proteins

    Author : Elmar Nurmemmedov; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; function; structure; transcription factor; cancer; affinity; kinetics; Biacore; RNA binding; DNA binding; Wilms tumour WT1 ; zinc finger;

    Abstract : The molecular process under which message in DNA is relayed onto RNA is called transcription, and it accomplished through involvement of so-called transcription factors. Zinc finger proteins are one of the most abundant classes of regulatory proteins in eukaryotic cells where they play central roles in a variety of cellular activities. READ MORE

  6. 4. Engineering membrane proteins for production and topology

    Author : Stephen Toddo; Daniel Daley; Roslyn Bill; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane protein; Over-expression; Protein production; Codon optimization; Escherichia coli; AraH; NarK; mRNA secondary structure; coding sequence; ribosome binding site; RBS; topology; split-GFP; Biochemistry; biokemi;

    Abstract : The genomes of diverse organisms are predicted to contain 20 – 30% membrane protein encoding genes and more than half of all therapeutics target membrane proteins. However, only 2% of crystal structures deposited in the protein data bank represent integral membrane proteins. READ MORE

  7. 5. Engineering microbial cell factories for protein production

    Author : Kiavash Mirzadeh; Daniel Daley; Grzegorz Kudla; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein production; expression vector; recombinant DNA; Translation initiation region; Escherichia coli; mRNA secondary structure; Synthetic evolution; Biochemistry; biokemi;

    Abstract : Proteins are often produced using microbial cell factories for academic or industrial purposes. Protein production is however not an open-and-shut procedure. Production yields often vary in an unpredictable and context dependent manner, limiting the rational design of a straightforward production experiment. READ MORE
