1. 31. The Plant Plasma Memrbane H+-ATPase: regulation by phosphorylation and 14-3-3 proteins

   Författare :Anne Olsson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phosphorylation; fusicoccin; 14-3-3; C-terminus; autoinhibitory domain; plasma membrane; plant; H -ATPase; Plant biochemistry; Växtbiokemi;

   Sammanfattning : The plant plasma membrane H+-ATPase is a predominant membrane enzyme that provides the energy for secondary active transport across the plasma membrane. Consequently, the H+-ATPase is thought to play a major role in many cell processes, and it is implicated to be regulated by a number of factors, including hormones, blue light, and fungal toxins The plant plasma membrane H+-ATPase is regulated via an autoinhibitory domain located within the C-terminal region of the enzyme.

3. 32. Calreticulins- Calcium-Binding Proteins with Functional Diversity and Evolutionary Duality

   Författare :Staffan Persson; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; plant; isoforms; evolution; diversity; differential regulation; chaperone; calnexin; calmegin; calcium; Arabidopsis; calreticulin; Växtbiokemi;

   Sammanfattning : Calreticulin is a multifunctional protein mainly localized in the endoplasmic reticulum in eukaryotic organisms, except yeasts. The protein comprises three distinct regions: the N-terminal N domain, the C-terminal C domain, and the central P domain, reflecting the functional diversity of calreticulin. LÄS MER

4. 33. The 14-3-3 protein family - Conserved structure, diverse functions

   Författare :Magnus Rosenquist; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; regulation; phosphorylation; plant; plasma membrane; fusicoccin; H ATPase; binding motifs; specificity; evolution; 14-3-3; isoforms; Plant biochemistry; Växtbiokemi;

   Sammanfattning : While once abstruse, 14-3-3 proteins are now well known as players in several cellular processes. These processes range from apoptosis and mitosis in mammals and yeast, to regulation of primary metabolism in plants. To date, 104 proteins have been shown to interact with 14-3-3s of which 85 are found in mammals and yeast, and 21 are found in plants. LÄS MER

5. 34. Wild plants can improve their rhizosphere chemistry in acid soils

   Författare :Marion Schöttelndreier; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; wild plants.; time pattern; soil heterogeneity; rhizotrons; rhizosphere; pH; oxalic acid; nutrient availability; malic acid; hydroponics; citric acid; 14C; biodegradation; acid soils; aluminium toxicity; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära; Plant biochemistry; Växtbiokemi;

   Sammanfattning : Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. LÄS MER

7. 35. Magnesium Chelatase: Insights into the first Step of Chlorophyll Biosynthesis

   Författare :Nick Sirijovski; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron microscopy; Proteobacteria; Mutants; Rhodobacter capsulatus; Tetrapyrrole; Plant biochemistry; Växtbiokemi; Biochemistry; Metabolism; Biokemi; metabolism; Proteins; enzymologi; enzymology; Proteiner; Chlorophyll biosynthesis; AAA proteins; Magnesium chelatase; Barley; ATPase;

   Sammanfattning : The enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). LÄS MER
