  1. 1. Physical Modeling of Protein Folding

    Author : Stefan Wallin; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; relativity; quantum mechanics; classical mechanics; three-helix bundle; similarity measure; Mathematical and general theoretical physics; protein dynamics; protein folding; two-state; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Wallin;

    Abstract : Sequence-based models for protein folding are developed and tested on peptides with both alpha- and beta-structure, and on small three-helix-bundle proteins. The interaction potentials of the models are minimalistic and based mainly on hydrogen bonding and effective hydrophobicity forces. READ MORE

  2. 2. Protein Folding Studied by Site Directed Mutagenesis

    Author : Tomas Ternström; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; Transition state; Activation Barrier; Two-State; Protein Folding; Protein Engineering;

    Abstract : The N-terminal RNA binding domain of U1A has been shown to fold in a two-state process without accumulating any intermediates. U1A has a symmetrically curved chevron plot which seems to result mainly from changes of the transition state. READ MORE

  3. 3. Statistical Physics of Protein Folding and Aggregation

    Author : Giorgio Favrin; Beräkningsbiologi och biologisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Two State; Physics; Fysik; Statistics; operations research; programming; aktuariematematik; programmering; operationsanalys; actuarial mathematics; Statistik; Simulations; Aggregation; Protein Folding; Fysicumarkivet A:2004:Favrin;

    Abstract : The mechanisms of protein folding and aggregation are investigated by computer simulations of all-atom and reduced models with sequence-based potentials. A quasi local Monte Carlo update is developed in order to efficiently sample proteins in the folded phase. READ MORE

  4. 4. 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

  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.
