  2. 6. Studies of Hyaluronan and Related Structures by NMR Spectroscopy

    Author : Yan Xue; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Hyaluronan (HA) is a natural polysaccharide in the glycosaminoglycan (GAG) family with repeating units of N-acetylglucosamine (GlcNAc) and glucuronic acid (GlcA), which are linked by β(1→4) and β(1→3) glycosidic linkages. HA has many important regulatory functions in the human body, but comprehension of its structure-function relationship remains limited. READ MORE

  4. 7. Development of NMR methods for studies of dynamics and structure : applications to motilin, Alzheimer β-peptide and ubiquitin

    Author : Peter Damberg; Ad Bax; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysics; biofysik;

    Abstract : NMR spin relaxation was used to study structure and dynamics of two biologically important peptides.The first case concerns the three-dimensional structure of the 22 amino acid residue peptide hormone motilin in the presence of SDS micelles, which mimic a biomembrane environment.

  5. 8. Molecular dynamics studied by NMR relaxation experiments. Characterization of functional dynamics in the FK506 binding protein FKBP12

    Author : Ulrika Brath; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear magnetic resonance; NMR; FK506; protein dynamics; chemical exchange; spin relaxation; FKBP12; FKBP; isotope labeling;

    Abstract : The presented thesis work is concerned with the study of molecular dynamics using liquid nuclear magnetic resonance (NMR) spectroscopy. Spin relaxation dispersion experiments in the rotating frame (R1ρ) are employed to provide a detailed, atomic-resolution view of protein dynamics. READ MORE

  6. 9. Protein structures and protein-solvent interactions : development and application of methods in high-resloultion nuclear magnetic resonance spectroscopy

    Author : Hannes Ponstingl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Nuclear magnetic resonance (NMR) spectroscopy in solution was used for the structural characterization of the proteins glutaredoxin-3 and flavodoxin from E. coli. A new NMR technique for the measurement of three-bond a proton-amide proton scalar coupling constants was developed. READ MORE

  7. 10. Experimental and Computational Magnetic Resonance Studies of Selected Rare Earth and Bismuth Complexes

    Author : Vasantha Gowda; Oleg Antzutkin; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : The rare-earth elements (REEs) and bismuth, being classified as the ‘most critical raw materials’ (European Raw Materials Initiatives, 2017), have a high economic importance to the EU combined with a high relative supply risk. REEs are highly important for the evolving technologies such as clean-energy applications, high-technology components, rechargeable batteries, permanent magnets, electric and hybrid vehicles, and phosphors monitors.
