  2. 1. Exploring the Molecular Dynamics of Proteins and Viruses

    Author : Daniel Larsson; David van der Spoel; Modesto Orozco; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; virus dynamics; capsid dissolution; satellite tobacco necrosis virus; satellite tobacco mosaic virus; virus genome structure; gas phase protein structure; water layer; micelle embedded protein; membrane protein; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Knowledge about structure and dynamics of the important biological macromolecules — proteins, nucleic acids, lipids and sugars — helps to understand their function. Atomic-resolution structures of macromolecules are routinely captured with X-ray crystallography and other techniques. READ MORE

  4. 2. Of spiders, bugs, and men : Structural and functional studies of proteins involved in assembly

    Author : Wangshu Jiang; Stefan D Knight; Steve J. Matthews; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein assembly; sulfate transporter; crystallography; Proteus mirabilis; fimbriae; adhesin; urinary tract infection; biofilm; spider silk; asymmetric dimer; Bri2; BRICHOS; molecular chaperone; Alzheimer s disease; amyloid; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Abstract : Protein assembly enables complex machineries while being economical with genetic information. However, protein assembly also constitutes a potential threat to the host, and needs to be carefully regulated.Sulfate is a common source of sulfur for cysteine synthesis in bacteria. READ MORE

  5. 3. Evolutionary and Pharmacological Studies of NPY and QRFP Receptors

    Abstract : The neuropeptide Y (NPY) system consists of 3-4 peptides and 4-7 receptors in vertebrates. It has powerful effects on appetite regulation and is involved in many other biological processes including blood pressure regulation, bone formation and anxiety. READ MORE

  6. 4. Antibiotic Resistance and the Cellular Currency S-adenosyl-methionine : Modification of aminoglycosides and nucleic acids

    Author : Sandesh Kanchugal P; Maria Selmer; Ditlev Brodersen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antibiotic resistance; streptomycin; spectinomycin; X-ray crystallography; methyltransferase; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Abstract : Streptomycin and spectinomycin are antibiotics that bind to ribosomes and inhibit protein synthesis. Common resistance mechanisms involve enzymatic modification of the two drugs by aminoglycoside nucleotidyltransferases (ANTs). The first part of this thesis covers the structural mechanism of two ANT enzymes. READ MORE

  7. 5. Structural and Biochemical Characterizations of Three Potential Drug Targets from Pathogens

    Author : Lu Lu; Sherry L Mowbray; Alwyn Jones; Christian Cambillau; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LepB; DXR; NDH-2; fosmidomycin; quinolinyl pyrimidine; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Abstract : As antibiotic resistance of various pathogens emerged globally, the need for new effective drugs with novel modes of action became urgent. In this thesis, we focus on infectious diseases, e.g. READ MORE
