  1. 1. Conformational Dynamics of Carbohydrates Studied by NMR Spectroscopy and Molecular Simulations

    Author : Jennie Östervall; Göran Widmalm; C. Allen Bush; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbohydrates; NMR; Molecular Dynamics; Conformation; Dynamics; Residual Dipolar Couplings; Cyclodextrins; Oligosaccharides; Organic chemistry; Organisk kemi;

    Abstract : Carbohydrates play important roles in biological processes. Their function is closely related to their conformation. In this thesis, conformational studies of carbohydrates by NMR spectroscopy and molecular dynamics computer simulations are described. READ MORE

  2. 2. Structural and conformational studies of bacterial polysaccharides employing NMR spectroscopy

    Author : Mikael Staaf; Jesus Jiminez-Barbero; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacterial polysaccharides; Magnetic resonance spectroscopy; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : Methods and approaches for performing structural and conformational analysis of bacterial polysaccharides in solution are described. The structure of one exopolysaccharide from Lactobacillus helveticus and two O-antigens from Escherichia coli have been determined using NMR spectroscopy, chemical degradation and mass spectrometry.

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; organisk kemi;

    Abstract : Methods for studies of the structures of carbohydrates in solution and their dynamics are presented. Approaches employing nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry (MS), force-field computer simulations and chemical methods are described. READ MORE

  4. 4. Characterising Halogen Bonding in a Cooperative Model System

    Author : Stefan Peintner; Mate Erdelyi; Anja Sandström; Uppsala universitet; []
    Keywords : Halogen Bond; NMR; peptide; conformation; RDC; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : Non-covalent interactions are the main driving factor for secondary structure formation of biomacromolecules and are of enormous importance for the direction of molecular recognition events, for example those of importance for drug discovery. Profound understanding of these interactions is of vital importance to achieve high affinity and selectivity of a ligand to a chosen target. READ MORE

  5. 5. Structural characterization of Deinococcus radiodurans phytochrome in solution

    Author : Lidija Vrhovac; Sebastian Westenhoff; Vladislav Orekhov; Magnus Wolf-Watz; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Biochemistry;

    Abstract : Phytochromes are red/far-red photoreceptors which control a wide spectrum of biological processes inplants, fungi, and bacteria. Although phytochromes have been extensively studied, their mechanism ofaction still remains elusive. The signaling mechanism suggested by crystal structures involves refoldingof the so-called PHY tongue. READ MORE
