  1. 11. Computational Prediction Models for Proteolytic Cleavage and Epitope Identification

    Författare :Liwen You; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; medical informatics; biomathematics biometrics; Bioinformatics; SVM; sequence analysis; rule extraction; protease-peptide interaction; OSRE; MHC; immunology; HIV; hierarchical method; HCV; Gaussian process; false positive; epitope; cleavage specificity; cleavage prediction; binding affinity; caspase; Bioinformatik; medicinsk informatik; biomatematik; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Binding affinity; Bioinformatics;

    Sammanfattning : The biological functions of proteins depend on their physical interactions with other molecules, such as proteins and peptides. Therefore, modeling the protein-ligand interactions is important for understanding protein functions in different biological processes. LÄS MER

  3. 12. Modeling of Protein Folding and Genetic Networks

    Författare :Fredrik Sjunnesson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; two-state folding; Protein folding; all-atom model; Mathematical and general theoretical physics; Kauffman model.; local update; Monte Carlo; classical mechanics; quantum mechanics; relativity; statistical physics; gravitation; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:2003:Sjunnesson;

    Sammanfattning : Models for potein folding are developed and applied to peptides and small proteins with both α-helix and β-sheet structure. The energy functions, in which effective hydrophobicity forces and hydrogen bonds are taken to be the two central terms, are sequence-based and deliberately kept simple. LÄS MER

  4. 13. Physical Modeling of Protein Folding

    Författare :Stefan Wallin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 14. Thermodynamics of Protein Folding and Design

    Författare :Erik Sandelin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; hydrophobicity; Monte Carlo; sequence analysis; sequence assembly; shotgun sequencing; Mathematical and general theoretical physics; classical mechanics; quantum mechanics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; thermodynamics; termodynamik; Fysicumarkivet A:2000:Sandelin; statistisk fysik; relativitet; protein design; klassisk mekanik; kvantmekanik;

    Sammanfattning : The protein folding and protein design problems are addressed, using coarse-grained models with only two types of amino acids, hydrophobic and hydrophilic. In addition to hydrophobicity forces, the models contain sequence-independent local interactions which are found to strongly influence the thermodynamics of these models. LÄS MER

  7. 15. Hydrophobicity Patterns in Protein Folding

    Författare :Frank Potthast; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; global optimization; multisequence; Fourier analysis; hydrophobicity; protein folding; simulated tempering; statistical physics; thermodynamics; Matematisk och allmän teoretisk fysik; kvantmekanik; klassisk mekanik; gravitation; relativitet; termodynamik; statistisk fysik; alpha-helix; protein design.; Mathematical and general theoretical physics; quantum mechanics; classical mechanics; relativity; Fysicumarkivet A:1998:Potthast;

    Sammanfattning : The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. LÄS MER
