  1. 11. Cryo-EM Studies of Macromolecular Complexes from Photosynthetic Organisms

    Författare :Annemarie Perez Boerema; Alexey Amunts; Mei Li; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cryo-EM; membrane proteins; photosynthesis; translation; chloroplast; ribosome; photosystem I; protein structure; Biochemistry; biokemi;

    Sammanfattning : Plants, algae, and cyanobacteria convert light energy into chemical energy through the process of photosynthesis, fueling the planet and making life as we know it possible. Photosystem I (PSI) is one of the main photosynthetic complexes, responsible for this process. LÄS MER

  3. 12. Coordination of two different genomes in response to light and stress

    Författare :Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

    Sammanfattning : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. LÄS MER

  4. 13. Protein phosphorylation and proteolysis - regulation and adaptive responses in photosynthesis

    Författare :Jens Forsberg; Avdelningen för molekylärmedicin och genterapi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; proteolysis; Plant biochemistry; protease; two-component systems; protein kinase; protein phosphorylation; state transitions; light-harvesting antenna; photosynthesis; chloroplast;

    Sammanfattning : Just as all other organisms, plants adapt to various environmental conditions. This work focuses on the role of chloroplast light harvesting complex II, LHCII, in adaptation of photosynthesis to changed light conditions. LÄS MER

  5. 14. Regulation of photosynthesis -Cytochrome b6f in redox regulation -Two novel proteases acting on an N-terminal peptide of LHCII

    Författare :Jörgen Ström; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; Växtbiokemi; cGEP; proteolysis; protease; protein phosphorylation; redox regulation; light-harvesting antenna; cytochrome b6f; chloroplast; Photosynthesis;

    Sammanfattning : In higher plants photosynthesis takes place in the chloroplast. This work focuses on two different processes that effects photosynthesis. Firstly, we studied the events occurring prior to the phosphorylation of LHCII. Secondly, we also studied two novel proteases, with the potential to degrade LHCII. LÄS MER

  7. 15. Nucleotide-Dependent Processes in the Thylakoid Lumen of Plant Chloroplasts

    Författare :Björn Lundin; Cornelia Spetea Wiklund; Zach Adam; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant; chloroplast; thylakoid; nucleotide; PSII; PsbO; Biology; Biologi;

    Sammanfattning : Plants, algae and photosynthetic bacteria are able to harvest the sunlight and use its energy to transform water and carbon dioxide to carbohydrate molecules and oxygen, both important to sustain life on Earth. This process is called photosynthesis and is the route by which almost all energy enters the biosphere. LÄS MER
