  1. 1. Regulation and transport mechanisms of eukaryotic aquaporins

    Författare :Madelene Palmgren; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aquaporin; Membrane protein; Transport; Glycerol; Aquaglyceroporins; Regulation; arsenite;

    Sammanfattning : Aquaporins are found in all kingdoms of life where they are involved in water homeostasis. They are small transmembrane water conducting channels that belong to the ancient protein family Major Intrinsic Proteins (MIP). LÄS MER

  3. 2. Molecular Metamorphosis in Transcriptional Regulation

    Författare :Malin Lüking; Johan Elf; Victor Muñoz; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein-DNA interactions; Facilitated diffusion; Binding Kinetics; Molecular Simulations; Fluorescence Microscopy; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : The foundation of all life is the interaction of molecules. Molecular interaction occurs in the tightly packed cytoplasm. In this crowded environment, the molecules need to be able to establish stable interactions with specific interaction partners, and with specific ones only. LÄS MER

  4. 3. Structural Details of Human Aquaporin Regulation : Three stories of three aquaporins

    Författare :Veronika Nesverova; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporin; membrane proteins; protein trafficking; water channel; aquaporin 0; aquaporin 5; aquaporin 2; cryo-EM; protein phosphorylation; protein-protein interaction; aquaporin regulation; aquaporins;

    Sammanfattning : Every cell is surrounded by a thin plasma membrane, protecting it from its surrounding. Specialized protein channels and transporters are embedded in this membrane, ensuring selective transport of molecules in and out of the cells. To maintain optimal hydration, water channels called aquaporins (AQPs) are present in every cell of our body. LÄS MER

  5. 4. Sequence- and structure guided engineering of proteins and enzymes for biotechnology and health applications

    Författare :Karen Schriever; Per-Olof Syrén; Elton P. Hudson; Eric A. Gaucher; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; enzymology; ancestral sequence reconstruction; antigen engineering; structural biology; terpene cyclases; enzyme thermodynamics; biocatalysis; phosphatases; allosteric regulation; Biotechnology; Bioteknologi;

    Sammanfattning : Proteins are highly diverse and sophisticated biomolecules that represent a cornerstone of biological structure and function and have been exploited in man-made applications for thousands of years. Those proteins that facilitate chemical reactions at physiologically relevant time-scales are referred to as enzymes. LÄS MER

  7. 5. Regulation of electron donation to photosystem 1

    Författare :Daniel Farkas; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPR; NMR; photosystem 1; plastocyanin; protein-protein interaction; PsaF;

    Sammanfattning : Photosynthesis is the process where energy from light is used to catalyze the formation of energy-rich molecules such as NADPH and ATP. These reactions are in fact the result of a long series of electron-transfer reactions where water molecules are the source of electrons and NADP+ is the terminal electron acceptor. LÄS MER
