  1. 1. Establishing the mechanistic basis of sugar transport

    Författare :Abdul Aziz Qureshi; David Drew; Magnus Wolf-Watz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane transport; transport energetics; nucleotide-sugar transporters; glucose transporters; malaria; cancer; Biochemistry; biokemi;

    Sammanfattning : Sugar is a vital molecule required for cell viability and homeostasis. Sugar is important for metabolic energy, energy storage, signaling, structure and osmolyte regulation. Transport of sugar represents an important physiological process. LÄS MER

  3. 2. Plastidial phosphate transport in plants

    Författare :Patrik Milton Karlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; phosphate transport; thylakoid membrane; root plastid; photosynthesis; leaf size; starch metabolism; homology modeling; site-directed mutagenesis;

    Sammanfattning : Phosphorus is an essential element for all living organisms and is central to the genetics and energetics of life. Inorganic phosphate (Pi) is recurrently involved in protein regulation and signal transduction but also in energy transfer as a component of the ATP-molecule. LÄS MER

  4. 3. Establishing the molecular mechanism of sodium/proton exchangers

    Författare :Povilas Uzdavinys; David Drew; Peter Brzezinski; M.D. Daniel Fuster; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; membrane protein; secondary active transporters; sodium proton exchangers; proton transport; structure; energetics; Biochemistry; biokemi;

    Sammanfattning : Sodium/proton exchangers are ubiquitous secondary active transporters that can be found in all kingdoms of life. These proteins facilitate the transport of protons in exchange for sodium ions to help regulate internal pH, sodium levels, and cell volume. LÄS MER

  5. 4. Characterization of a new amino acid transport system in human epidermal Langerhans cells

    Författare :Niels Bendsöe; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amino acid transport; energy charge; epidermis; glycolysis; lactate; Langerhans cells; L-dopa; mitochondria; omeprazole; Dermatology; venereology; Dermatologi; venereologi;

    Sammanfattning : Based on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. LÄS MER

  7. 5. Charge and Energy Transport in Disordered Organic Semiconductors

    Författare :Hassan Abdalla; Martijn Kemerink; Ronald Österbacka; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Improvement of the performance of organic disordered semiconductors (OSC) is driven by the understanding   of the underlying charge transport mechanisms and systematic exploitation thereof. There exists a multitude of materials and material systems based on polymers and small molecules with promising performance for use in organic light emitting diodes, photovoltaics, organic field-effect transistors and thermoelectrics.
