  1. 1. Membrane Protein Biogenesis in Escherichia coli : A proteomics approach

    Författare :David Vikström; Jan-Willem de Gier; Eitan Bibi; Stockholms universitet; []
    Nyckelord :SRP; YidC; SecE; Membrane protein biogenesis; protein targeting; 2D BN SDS-PAGE; Biochemistry; biokemi;

    Sammanfattning : In the bacterium Escherichia coli all proteins are synthesized in the cytoplasm. However, at least 25% of them then need to be exported to another cellular compartment where they exert their function. E. coli has several different targeting pathways to ensure the correct localization of its proteins. LÄS MER

  3. 2. Human Aquaporins: Production, Characterization and Interactions

    Författare :Jennie Sjöhamn; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporins; membrane protein; protein production; protein characterization; protein:protein interactions; structural biochemistry;

    Sammanfattning : Membrane proteins are essential components of the cell and responsible for the communication with the outside environment and transport of molecules across the membrane. Water transport is facilitated by aquaporins, which are water selective transmembrane pores that serve to maintain cell homeostasis. LÄS MER

  4. 3. Light’EM up! : structural characterization of light-driven membrane protein complexes by cryogenic electron microscopy

    Författare :André Tomás Graça; Wolfgang P. Schröder; Johannes Messinger; Karina Persson; Werner Kühlbrandt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 3D reconstruction; Arabidopsis thaliana; assembly; chlorophyll; cryo-EM; cyanobacteria; Deinococus radiodurans; electron; land plants; membrane protein complexes; Photosystem II; proton; single-particle analysis; S-Layer Deinoxanthin Binding Complex SDBC ; water.; Biochemistry; biokemi; biologisk kemi; biological chemistry;

    Sammanfattning : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. LÄS MER

  5. 4. Protein complexes in chlorophyll biosynthetic enzymes

    Författare :Ragna Peterson Wulff; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; mass spectrometry; Rhodobacter capsulatus; barley; cyclase; magnesium chelatase; chlorophyll biosynthetic pathway; Protein complex;

    Sammanfattning : Proteins are found on the inside, in the membrane, on the surface and on the outside of cells. They form complicated structures and they interact with other molecules and proteins. LÄS MER

  7. 5. 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
