  2. 1. In vivo analysis of amino acid permease folding in yeast

    Author : Andreas Ring; Per O. Ljungdahl; George Diallinas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; endoprotease; subcellular fractionation; membrane-localized chaperone; amino acid permease; endoplasmic reticulum; membrane protein folding; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Abstract : Plasma membrane (PM) proteins are critical for cells to respond to environmental cues, such as the availability of nutrients. The yeast Saccharomyces cerevisiae is able to sense extracellular amino acids using the SPS sensing system. READ MORE

  4. 2. Regulatory mechanisms of amino acid-induced signaling in Saccharomyces cerevisiae

    Author : Deike J. Omnus; Per O. Ljungdahl; Claudio De Virgilio; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; regulatory mechanisms; nutrient sensing; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Abstract : This thesis describes studies aimed at elucidating the molecular mechanisms that regulate the SPS (Ssy1-Ptr3-Ssy5) signal transduction pathway in the yeast Saccharomyces cerevisiae. This pathway is induced by extracellular amino acids and facilitates their uptake. READ MORE

  5. 3. The occurrence of amino acids in agricultural soil and their uptake by plants

    Author : Sandra Jämtgård; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The ability of plants to take up amino acids is widespread among plants, but the ecological and physiological implications of this ability are not fully understood. Therefore, in the investigations this thesis is based upon, key aspects of the uptake of amino acids by agricultural plants were explored in field studies (to ensure ecological relevance) and laboratory analyses (to ensure precision).

  6. 4. Genetic and biochemical characterization of a novel sensor of extracellular amino acids in yeast

    Author : Hanna Forsberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Eukaryotic cells make developmental decisions that initiate distinct programs of gene expression. In the yeast Saccharomyces cerevisiae the majority of decisions affecting developmental outcomes are made in response to extra- and intracellular derived nutritional signals. READ MORE

  7. 5. Ligand-activated proteolysis in nutrient signaling

    Author : Claes Andréasson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cells respond to changing nutrient availability and make adjustments in physiological processes. Central for making proper adjustments is the ability to execute appropriate changes in patterns of gene expression. READ MORE
