  1. 1. On folding of coated papers

    Author : Christophe Barbier; Per-Lennart Larsson; Tetsu Uesaka; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; folding; coated papers; finite element method; cracking; indentation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The mechanical behaviour of coated papers during folding has been investigated. This problem has been studied with experimental techniques and numerical analyses in order to give a better understanding of the folding properties of coated papers pertinent to the mechanical behaviour in general, and particularly cracking along the fold.

  2. 2. Protein folding without loops and charges

    Author : Martin Kurnik; Mikael Oliveberg; Kevin W. Plaxco; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; protein folding; folding cooperativity; protein aggregation; protein charges; protein engineering; biokemi; Biochemistry;

    Abstract : Going down the folding funnel, proteins may sample a wide variety of conformations, some being outright detrimental to the organism. Yet, the vast majority of polypeptide molecules avoid such pitfalls. Not only do they reach the native minimum of the energy landscape; they do so via blazingly fast, biased, routes. READ MORE

  3. 3. 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 : NATURAL SCIENCES; NATURVETENSKAP; 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. 4. Studies on spinach plastocyanin and mutants : Expression in Escherichia coli, folding and function

    Author : Mikael Ejdebäck; Örjan Hansson; Miguel A. De la Rosa; Göteborgs Universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; plastocyanin; electron transfer; copper; protein-protein interactions; protein expression; folding; site-directed mutagenesis; NMR; Naturvetenskap; Natural sciences;

    Abstract : Photosynthesis is a process in which photons from sunlight excite chlorophylls in the thylakoid membranes of plants, algae and cyanobacteria. The photo-oxidised reaction centre chlorophyll P700 is re-reduced by an electron transferred from the soluble, blue copper protein plastocyanin. READ MORE

  5. 5. Folding of the Ribosomal protein S6 : The role of sequence connectivity, overlapping foldons, and parallel pathways

    Author : Ellinor Haglund; Mikael Oliveberg; Neil Ferguson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; protein folding; protein stability; two-state folding; S6; chevron plot; transition state; parallell pathways; foldon; two-channel landscape; protein engineering; H D-exchange; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : To investigate how protein folding is affected by sequence connectivity five topological variants of the ribosomal protein S6 were constructed through circular permutation.  In these constructs, the chain connectivity (i.e. the order of secondary-structure elements) is changed without changing the native-state topology.
