  1. 1. Human copper ion transfer : from metal chaperone to target transporter domain

    Författare :Moritz Sebastian Niemiec; Pernilla Wittung-Stafshede; Nigel Robinson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; copper homeostasis; copper chaperone; Atox1; ATP7B; Wilson disease protein; metal transport; size exclusion chromatography; thermodynamics; isothermal calorimetry;

    Sammanfattning : Many processes in living systems occur through transient interactions among proteins. Those interactions are often weak and are driven by small changes in free energy. LÄS MER

  3. 2. Synthesis, conformational analysis, and biological evaluation of peptides from E. coli P pilus proteins

    Författare :Katarina Flemmer Karlsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; CD spectroscopy; peptide structure; ELISA; solid-phase peptide synthesis; peptide; P pili; chaperone; Organic chemistry; Organisk kemi;

    Sammanfattning : Many bacteria utilize hairlike protein appendages (pili) to attach themselves to mucosal cell surfaces in the host organism. The pilus is assembled from protein subunits synthesized inside the bacteria and transported to the outer cell wall for incorporation into the growing pilus. LÄS MER

  4. 3. A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes

    Författare :Ulrika Härndahl; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; a-crystallin; sHsp; chaperone; amphipathic a-helix; oligomer; redox-regulated; methionine sulfoxidation; oxidative stress; regulation; protein structure; circular dichroism; mass spectrometry; fluorescence spectroscopy; Biochemistry; Metabolism; Biokemi;

    Sammanfattning : A specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. LÄS MER

  5. 4. Characterization of auxiliary membrane proteins in the chloroplast of Arabidopsis thaliana

    Författare :Lotta von Sydow; Christiane Funk; Wolfgang Schröder; Thomas Pfannschmidt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Arabidopsis; chaperone; chloroplast; Cytochrome b559; FtsH; membrane proteins; photosynthesis; Photosystem II; protease; PsbY.; Arabidopsis; chaperone; Cytochrome b559; fotosyntes; fotosystem II; FtsH; kloroplast; membranprotein; proteas; PsbY.; biokemi; Biochemistry;

    Sammanfattning : In nature, sessile plants have to adapt to their environment and to the never ending changes they are exposed to. They do so mainly by proteomic and metabolomic changes. In all cells, there are complex networks of auxiliary proteins that are responsible for quality control of all the cell's proteins. LÄS MER

  7. 5. Deg/HtrA proteases of the cyanobacterium Synechocystis sp. PCC 6803 : from biochemical characterization to their physiological functions

    Författare :Xuân Tâm Lâm; Christiane Funk; Jörg Nickelsen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deg; HtrA; protease; chaperone; Synechocystis sp. PCC 6903; biochemical characterization; physiological function; proteomics; structure;

    Sammanfattning : The family of Deg/HtrA proteases is present in a wide range of organisms from bacteria, archaea to eukaryota. These ATP-independent serine endopeptidases play key roles in the cellular protein quality control. The cyanobacterium Synechocystis sp. LÄS MER
