  1. 1. Of spiders, bugs, and men Structural and functional studies of proteins involved in assembly

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Wangshu Jiang; Uppsala universitet.; [2018]
    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

  2. 2. Structural studies of proteins in apoptosis and lipid signaling

    University dissertation from Stockholm : Institutionen för biokemi och biofysik

    Author : Maria Dolores Herman Moreno; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; proteins; crystal structure; apoptosis; cancer; CoFi-Blot; kinases; lipid signaling; NATURAL SCIENCES Chemistry Biochemistry Structural biology; NATURVETENSKAP Kemi Biokemi Strukturbiologi; Structural Biology; strukturbiologi;

    Abstract : Signaling pathways control the fate of the cell. For example, they promote cell survival or commit the cell to death (apoptosis) in response to cell injury or developmental stimuli, decisions, which are vital for the proper development and functioning of metazoan. READ MORE

    Abstract : A large number of proteins require certain metals to stabilize their structures or to function properly. About one third of all proteins in the Protein Data Bank (PDB) contain metals and it is estimated that approximately the same proportion of all proteins are metalloproteins. READ MORE

  4. 4. Exploring Unorthodox Aquaporins : Characterization of NbXIPs & AtNIPs

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Biochemistry and Structural Biology

    Author : Henry Ampah-Korsah; Lund University.; Lunds universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aquaporins; XIPs; NIPs; Phosphorylation; Pichia pastoris; Overexpression; boric acid; membrane proteins;

    Abstract : AbstractAquaporins are membrane integral proteins that facilitate the transport of waterand/or other small neutral molecules across biological membranes in cells in allforms of life. Among the subfamilies of aquaporins in higher plants, the X IntrinsicProteins (XIPs) are the most recently discovered subfamily and the leastcharacterized. READ MORE

  5. 5. To reduce a ribonucleotide – Radical solutions in enzymology in form and function

    University dissertation from Department of Biochemistry and Structural Biology, Lund University

    Author : Oskar Aurelius; Lund University.; Lunds universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribonucleotide reductase; X-ray crystallography; Small-angle X-ray scattering; nucleotide metabolism; protein biophysics; metalloproteins; anaerobic enzymology;

    Abstract : It has been more than 50 years since the enzyme system ribonucleotide reductase (RNR), catalysing the reduction of ribonucleotides to deoxyribonucleotides, was first discovered. RNR was also the first time that radical chemistry was revealed in an enzyme. READ MORE
