  1. 1. The cell biology and catalytic properties of the nutrient-induced signaling endoprotease Ssy5

    Författare :António Martins; Per O. Ljungdahl; Bruno André; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; regulated proteolysis; endoprotease; serine protease; substrate specificity; subcellular fractionation; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Sammanfattning : Cells continuously sense and respond to changes in the presence, quality and quantity of external and internal nutrients. Specific signaling proteases have been identified based on their roles in processing or destruction of distinct sets of downstream effector proteins in response to environmental cues. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. In vivo analysis of amino acid permease folding in yeast

    Författare :Andreas Ring; Per O. Ljungdahl; George Diallinas; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. The Role of Proline Catabolism in Candida albicans Pathogenesis

    Författare :Fitz Gerald S. Silao; Per O. Ljungdahl; Joachim Morschhäuser; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Candida albicans; proline metabolism; ATP; P5C; virulence; macrophage; hyphae; filamentation; Ras1 cAMP PKA; mitochondria; Proline dehydrogenase; P5C dehydrogenase; reactive oxygen species; Proline-P5C cycle; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Candida albicans is an opportunistic fungal pathogen that has evolved in close association with human hosts. Pathogenicity is linked to an array of virulence characteristics expressed in response to environmental cues and that reflect the requirement to take up and metabolize nutrients available in the host.
