  1. 1. Perplexing Protein Puzzles

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  4. 4. NMR Studies of Bacterial Albumin-Binding Modules

    Author : Maria U Johansson; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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;

    Abstract : 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. READ MORE

  5. 5. Evolution of cellular complexity and other remarkable features in Gemmataceae : Complex bacterial lineages defy prokaryotic trends

    Abstract : Bacteria of the family Gemmataceae belong the phylum Planctomycetes and are remarkable because of their complex cellular architectures, previously considered to be traits exclusive to eukaryotes. This thesis provides clues to the atypical cell envelope, the enhanced radiotolerance and the amazing cellular complexity of these bacteria. READ MORE
