  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 :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 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

  2. 2. Development of a Yeast Model for Functional Analysis of Human Copper Transport Proteins

    Författare :Kumaravel Ponnandai Schanmugavel; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; luminal loop; metal binding domains; Wilson’s disease protein; yeast model; ATP7B; copper transport.;

    Sammanfattning : ABSTRACT Copper (Cu) is an important trace element that plays a vital role in several biological processes. It mediates numerous biochemical functions to maintain cellular homeostasis making it an essential metal for sustaining life. LÄS MER

  3. 3. The use of fluorescence techniques for the study of some membrane-bound photosynthetic properties and some effects of copper on the thylakoid membrane

    Författare :Göran Samuelsson; N. Valanne; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; chlorophylI-protein complexes; sequential extraction; ß-carotene low temperature fluorescence emission; absorption; in vivo chi. a fluorescence; copper; electron transport;

    Sammanfattning : Lyophilized pea chloroplasts were extracted in a stepwise manner in an organic solvent (petroleum ether) with increasing polarity which was obtained by addition of small amount of ETOH (0-1 %). Absorption and low temperature fluorescence emission spectra were measured on both the extracted thylakoids and on isolated chlorophylI-protein complexes. LÄS MER

  4. 4. Transport of Heavy Metals in Soil Subjected to an Electric Field -A Study of the Transport of Copper in Bentonite Clay

    Författare :Klas Arnerdal; KTH; []
    Nyckelord :Electrokinetic soil remediation; bentonite; copper; adsorption; electromigration; electroosmosis; pH; potential;

    Sammanfattning : This licentiate thesis addressesphosphorus release from sewage sludge, which is the first stepin phosphorus recovery. The concept ofphosphorus recovery maybe seen as a part of sustainable sludge handling in that it isa means of recycling resources without supplying harmfulsubstances to humans or the environment.

  5. 5. Tracing Copper from society to the aquatic environment : Model development and case studies in Stockholm

    Författare :Qing Cui; Maria E. Malmström; Olle Wahlberg; KTH; []
    Nyckelord :diffuse source; source analysis; sediment pollution levels; urban lake; Copper; Stockholm archipelago; SFA; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Copper remains at elevated levels in the aquatic environment of Stockholm due to diffuse urban sources. Management of these diffuse sources requires their quantification but they cannot be measured directly by field observations. LÄS MER
