  1. 1. Peroxiredoxins in Redox Signaling and Aging

    Författare :Friederike Roger; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aging; Peroxiredoxin; Redox Signaling; Caloric restriction; light sensing;

    Sammanfattning : Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not clear through what mechanism peroxiredoxins extend lifespan. LÄS MER

  3. 2. Overview and characterisation of the thylakoid lumen of higher plants

    Författare :Ulrika Petersson; Wolfgang Schröder; Christine H. Foyer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arablidopsis; thylakoid lumen; AtCYP20-2; Peroxiredoxin Q; oxidative stress; Biochemistry; Biokemi;

    Sammanfattning : In higher plants, chloroplasts are the site for the photosynthetic reactions, converting solar energy to chemical energy. Within the chloroplast the thylakoid membrane network encloses the soluble lumen compartment. LÄS MER

  4. 3. Proteostasis and Aging in Saccharomyces cerevisiae - The role of a Peroxiredoxin

    Författare :Sarah Hanzén; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Aging; Caloric restriction; Oxidative stress; Peroxiredoxins; Proteostasis; Protein aggregates; Ubiquitin-proteasome system;

    Sammanfattning : Aging is characterized by a progressive decline in physiological functions that limits biological processes, increases the risk of disease, and ultimately leads to death. At the cellular level, aging is associated with accumulation of damaged components, including proteins, indicating that protein homeostasis (or proteostasis) fails to maintain the integrity and functionality of the proteome as cells age.

  5. 4. Protein complexes in chlorophyll biosynthetic enzymes

    Författare :Ragna Peterson Wulff; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; mass spectrometry; Rhodobacter capsulatus; barley; cyclase; magnesium chelatase; chlorophyll biosynthetic pathway; Protein complex;

    Sammanfattning : Proteins are found on the inside, in the membrane, on the surface and on the outside of cells. They form complicated structures and they interact with other molecules and proteins. LÄS MER

  7. 5. On chaperone co-operation in temporal and spatial protein quality control

    Författare :Rebecca Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular chaperones; Heat shock proteins; Hsp70 chaperones; Proteostasis; Ageing; Asymmetric damage segregation; Peroxiredoxins; Spatial protein quality control;

    Sammanfattning : In order for a protein to be able to function correctly it needs to adopt its proper fold. Because of this, protein quality control (PQC) is vital at every level of cellular function. The central protein in PQC networks across all kingdoms of life are the Hsp70 molecular chaperones. LÄS MER
