  2. 1. The birth and growth of the protein folding nucleus : Studies of protein folding focused on critical contacts, topology and ionic interactions

    Author : Linda Hedberg; Mikael Oliveberg; Christopher Johnson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein folding; protein stability; two-state folding; chevron plot; transition-state movements; Hammond behaviour; topology; electrostatic interactions; pH dependence; mass-action; protein engineering; pKa; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Proteins are among the most complex molecules in the cell and they play a major role in life itself. The complexity is not restricted to just structure and function, but also embraces the protein folding reaction. READ MORE

  4. 2. From protein sequence to structural instability and disease

    Author : Lixiao Wang; Uwe Sauer; Sven Hovmöller; Umeå universitet; []
    Keywords : protein domain; remote homologue; intrinsically disorder unstructured proteins; protein function; point mutation; protein family protein stability; HMMs; CRFs; SVMs;

    Abstract : A great challenge in bioinformatics is to accurately predict protein structure and function from its amino acid sequence, including annotation of protein domains, identification of protein disordered regions and detecting protein stability changes resulting from amino acid mutations. The combination of bioinformatics, genomics and proteomics becomes essential for the investigation of biological, cellular and molecular aspects of disease, and therefore can greatly contribute to the understanding of protein structures and facilitating drug discovery.

  5. 3. Structural Studies of Binding Proteins: Investigations of Flexibility, Specificity and Stability

    Author : Ulrika Magnusson; Sherry L. Mowbray; Anthony J. Wikinson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Periplasmic binding protein; X-ray crystallography; conformational change; acidophile; protein specificity; protein structure; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Binding proteins are present both in gram-negative and gram-positive bacteria. They are the recognition components of the ABC transport systems that transport different nutrients into the cell, and are in some cases also involved in chemotaxis. READ MORE

  6. 4. The effect of sequence truncation and amino-acid substitutions on the biophysical properties of protein S and calbindin D9k

    Author : Karin Julenius; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface plasmon resonance; fluorescence spectroscopy; circular dichroism spectroscopy; NMR spectroscopy; hydrophobic effect; protein stability; dimerization; cooperativity; calcium binding; EGF-module; EF-hand; calbindin D9k; protein S; synthet; Physical chemistry; Fysikalisk kemi;

    Abstract : Protein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. READ MORE

  7. 5. Prediction, Design and Determination of Protein Structures

    Author : Sebastian Rämisch; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein design; Rosetta; Fold-and-Dock; leucine rich repeat proteins; coiled-coils; molecular replacement; ab initio phasing; temperature stability; fluorescent proteins;

    Abstract : The three-dimensional structure of protein is encoded in its amino acid sequence. Modern structure prediction algorithms make it possible to predict the structure of small proteins using sequence information alone. READ MORE
