  1. 16. Plastidial phosphate transport in plants

    Författare :Patrik Milton Karlsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; phosphate transport; thylakoid membrane; root plastid; photosynthesis; leaf size; starch metabolism; homology modeling; site-directed mutagenesis;

    Sammanfattning : Phosphorus is an essential element for all living organisms and is central to the genetics and energetics of life. Inorganic phosphate (Pi) is recurrently involved in protein regulation and signal transduction but also in energy transfer as a component of the ATP-molecule. LÄS MER

  3. 17. Elongation factor 2: A key component of the translation machinery in eukaryotes : Properties of yeast elongation factor 2 studied in vivo

    Författare :Galyna Bartish; Odd Nygård; Suparna Sanyal; Stockholms universitet; []

    Sammanfattning : Synthesis of proteins is performed by the ribosome, a large ribonucleoprotein complex. Apart from the ribosome, numerous protein factors participate in this process. Elongation factor 2 (eEF2) is one of these factors. eEF2 is an essential protein with a mol. LÄS MER

  5. 19. The structural basis for the catalytic specificity of manganese lipoxygenases : 3D structure analysis of the lipoxygenase of Magnaporthe oryzae

    Författare :Anneli Wennman; Ernst H. Oliw; Marcia Newcomer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; oxylipin; lipoxygenase; crystal structure; crystallography; HPLC; mass spectrometry; yeast; site-directed mutagenesis; fungi; Biochemical Pharmacology; Biokemisk farmakologi;

    Sammanfattning : Lipoxygenases (LOX) catalyze regio- and stereospecific oxygenation of polyunsaturated fatty acids to hydroperoxides. These hydroperoxides are further metabolized to leukotrienes and lipoxins in mammals, and are involved in asthma and inflammation. LOX of animals and plants contain iron as catalytic metal (FeLOX).

  7. 20. Functional Studies of the Neuropeptide Y System : Receptor-Ligand Interaction and Regulation of Food Intake

    Författare :Helena Åkerberg; Dan Larhammar; Rickard Malmström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropeptide Y; G-protein coupled receptor GPCR ; site-directed mutagenesis; pancreatic polypeptide; food intake; dog; Pharmacology; Farmakologi;

    Sammanfattning : The members of the mammalian neuropeptide Y family, i.e. the peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP), are all involved in regulation of food intake. In human and most other mammals they act via receptors Y1, Y2, Y4 and Y5. LÄS MER
