  1. 1. Perplexing Protein Puzzles

    Författare :Stina Lindman; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; calbindin D9k; split-GFP; protein G B1; pKa-values; protein reconstitution; Electrostatic interactions; protein stability; protein denaturation; heteronuclear NMR; pH titrations;

    Sammanfattning : Protein structure and stability are inherent in the amino acid sequence and governed by non-covalent interactions. The cooperation between forces is, however, perplexing and not well understood. In order to elucidate and predict protein folding and stability, detailed studies of non-covalent interactions are required. LÄS MER

  3. 2. Theoretical and Biochemical : Advancing Protein Structure Investigations with Complementing Computations

    Författare :Maxim N. Brodmerkel; Erik G. Marklund; Carl Caleman; Charlotte Uetrecht; Helmut Grubmüller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics simulation; Protein structure; Structural biology; Protein hydration; Electric dipole; Collision Induced Unfolding;

    Sammanfattning : Life as we know it today would not exist without proteins. The functions of proteins for us and other organisms are linked to their three-dimensional structures. As such, protein structure investigations are a crucial contribution for understanding proteins and the molecular basis of life. LÄS MER

  4. 3. The paralemmin protein family : Phosphoproteins involved in filopodia and dendritic spine formation

    Författare :Nicole G. Neumann; Klas Kullander; Karin Nordström; Eirc Hanse; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Dendritic spines, which connect neurons with each other, constitute most of the excitatory synapses and undergo experience-dependent neuronal plasticity. The function of dendritic spines and their synaptic strength are highly correlated with morphological changes. LÄS MER

  5. 4. Protein Engineering of Candida antarctica Lipase A : Enhancing Enzyme Properties by Evolutionary and Semi-Rational Methods

    Författare :Anders G. Sandström; Jan-Erling Bäckvall; Uwe T. Bornscheuer; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lipase; protein engineering; directed evolution; kinetic resolution; structural biology; Enzyme engineering; Enzymteknik; organisk kemi; Organic Chemistry;

    Sammanfattning : Enzymes are gaining increasing importance as catalysts for selective transformations in organic synthetic chemistry. The engineering and design of enzymes is a developing, growing research field that is employed in biocatalysis. LÄS MER

  7. 5. NMR Studies of Bacterial Albumin-Binding Modules

    Författare :Maria U Johansson; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi; Physical chemistry; three-helix bundle; protein structure; protein PAB; protein-protein interactions; protein G; protein dynamics; NMR; module shuffling; GA module; evolution; albumin-binding; bacterial surface proteins;

    Sammanfattning : Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. LÄS MER
