  2. 21. 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 : 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

  4. 22. Interactions Between Small Heat Shock Proteins and Substrate Proteins Mass Spectrometric Detection of Crosslinked Peptides to Map Protein-Protein Interactions

    Author : Emma Åhrman; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein-protein interactions; Small heat shock proteins; Mass spectrometric peptide mapping; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : The small heat shock proteins (sHsps) are a widespread class of molecular chaperones existing in all organisms. During heat stress the sHsps protect other proteins from unfolding and aggregation. In plants the sHsps play an especially prominent part of the stress response. READ MORE

  5. 23. Protein aggregation: Computational modeling and Monte Carlo algorithm development

    Author : Sigurdur Jonsson; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; protein aggregation; disordered proteins; Fysicumarkivet A:2014:Jonsson;

    Abstract : Although organisms have evolved sophisticated cellular mechanisms for regulating their various protein networks, proteins sometimes start to clump together in an uncontrolled way. The aggregation of proteins has been associated with a range of serious diseases. READ MORE

  6. 24. Temperature-dependent structure and function of group A streptococcal M proteins

    Author : Tommy Cedervall; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; plasma protein; fibrinogen; temperature; hydrophobicity; coiled-coil; Ig-binding; M protein; group A streptococcus; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Temperature-dependent structure and function of group A streptococcal M proteins.This thesis describes the temperature-dependent structure of the members in the group A streptococcal M protein family. M proteins are cell-surface proteins that are important for the bacterial virulence and bind to a diverse set of human plasma proteins. READ MORE

  7. 25. Folding and Structure of Azurin - The Influence of a Metal

    Author : Johan Leckner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; azurin; metal cofactor; disulfide bond; protein folding; solution structure; protein stability; paramagnetic NMR;

    Abstract : The structural role of the metal in the protein azurin from Pseudomonas aeruginosa has been a long standing question. Azurin belongs to the cupredoxin family and is a 128 residue beta-barrel protein of greek-key topology. READ MORE
