1. 1. Time-resolved Structural and Mechanistic Studies of Water Oxidation in Photosystem II : water here, water there, water everywhere

   Författare :Casper de Lichtenberg; Johannes Messinger; Wolfgang P. Schröder; Holger Dau; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Oxygenic Photosynthesis; Photosystem II; TR-MIMS; isotope exchange; EPR; EDNMR; water splitting; water oxidation;

   Sammanfattning : Oxygenic photosynthesis is undisputedly one of the most important chemical processes for human life on earth as it not only fills the atmosphere with the oxygen that we need to breathe, but also sustains the accumulation of biomass, which is not only used as nourishment but is also present in almost every aspect of our lives as building material, textiles in clothes and furniture, or even as living decorations to name a few.The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which is embedded in the thylakoid membranes of plants, algae and cyanobacteria.

3. 2. Functions of REP27 and the low molecular weight proteins PsbX and PsbW in repair and assembly of photosystem II

   Författare :Jose Gines Garcia Cerdan; Wolfgang Schröder; Eva-Mari Aro; Umeå universitet; []
   Nyckelord :Photosynthesis; photosystem II reaction center; PSII-LHCII supercomplex; antisense plant; T-DNA knockout plant; auxiliary protein; Biochemistry; biokemi;

   Sammanfattning :     Oxygenic photosynthesis is the major producer of both oxygen and organic compounds on earth and takes place in plants, green algae and cyanobacteria. The thylakoid membranes are the site of the photosynthetic light reactions that involve the concerted action of four major protein complexes known as photosystem II (PSII), cytochrome b6f complex, ATP synthase and photosystem I (PSI).

4. 3. Proteomic analysis of Arabidopsis thaliana

   Författare :Irene Granlund; Wolfgang Schröder; Birte Svensson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteomic; speclust; post-translational modification; DIGE; plastocyanin; TL29; APX; thylakoid lumen; chloroplast stroma; Biochemistry; Biokemi;

   Sammanfattning : A complete proteome analysis of the chloroplast stroma, using 2D-PAGE, from spinach and Arabidopsis was performed. To improve the identification of proteins a computer program named SPECLUST was used. LÄS MER

5. 4. The chloroplast lumen : New insights into thiol redox regulation and functions of lumenal proteins

   Författare :Michael Hall; Wolfgang Schröder; Bob B. Buchanan; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photosynthesis; thylakoid lumen; thioredoxin; pentapeptide repeat; proteomics; Biochemistry; biokemi;

   Sammanfattning : In higher plants oxygenic photosynthesis primarily takes place in the chloroplasts of leaves. Within the chloroplasts is an intricate membrane system, the thylakoid membrane, which is the site of light harvesting and photosynthetic electron transport. LÄS MER

7. 5. Structural biology studies of thylakoid lumen proteins required for photosystem II assembly and function

   Författare :Roland Locmelis; Uwe Sauer; Wolfgang Schröder; Inger Andersson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structural biology; x-ray crystallography; cloning; protein expression; HCF136; LPA19; MPH2; Prx6; photosynthesis; thylakoid lumen PSII;

   Sammanfattning : Little is known about the structures and functions of thylakoid lumen proteins. However, some of these proteins have an essential role in photosynthesis. LÄS MER
