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

    Författare :Wangshu Jiang; Stefan D Knight; Steve J. Matthews; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
