    Sammanfattning : By cleaving peptide bonds, proteases either activate or degrade proteins and maintain protein quality control in response to various developmental stimuli and environmental factors. My work has focused on elucidating the role of the filamentation temperature sensitive protein H (FtsH) proteases. LÄS MER

    Sammanfattning : In nature, sessile plants have to adapt to their environment and to the never ending changes they are exposed to. They do so mainly by proteomic and metabolomic changes. In all cells, there are complex networks of auxiliary proteins that are responsible for quality control of all the cell's proteins. LÄS MER

  4. 3. The Role of Proteases in Plant Development

    Författare :Maribel Garcia-Lorenzo; Christiane Funk; Zach Adam; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Comparative genomics; protease; PCD; leaf senescence; FtsH; Arabidopsis; Populus; Biochemistry; Biokemi;

    Sammanfattning : Proteases play key roles in plants, maintaining strict protein quality control and degrading specific sets of proteins in response to diverse environmental and developmental stimuli. Similarities and differences between the proteases expressed in different species may give valuable insights into their physiological roles and evolution. LÄS MER

  5. 4. Characterization of FtsH proteases in the annual plant Arabidopsis thaliana

    Författare :Harald Aigner; Christiane Funk; Sacha Baginsky; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : Background FtsH is an ATP-dependent membrane-bound metalloprotease. A. thaliana contains 12 FtsH proteases localized in membranes of chloroplasts and mitochondria where they form homo- or hetero-hexameric complexes. FtsH11 – the main subject of this thesis – is located in the chloroplast envelope. LÄS MER

  7. 5. FtsH protease and ClpG disaggregase confer fitness advantages to the worldwide prevalent Pseudomonas aeruginosa clone C

    Författare :Shady Mansour Kamal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pseudomonas aeruginosa is an environmental bacterium and a frequent nosocomial pathogen causing a wide range of opportunistic infections, especially in immunocompromised patients. Clone C is one of the most prevalent groups of closely related strains distributed worldwide in the environment, such as in natural aquatic habitats, and the clinical settings, such as in patients with an underlying functional impairment of the cystic fibrosis transmembrane conductance regulator.
