1. 21. Studies on spinach plastocyanin and mutants : Expression in Escherichia coli, folding and function

   Författare :Mikael Ejdebäck; Örjan Hansson; Miguel A. De la Rosa; Göteborgs Universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plastocyanin; electron transfer; copper; protein-protein interactions; protein expression; folding; site-directed mutagenesis; NMR; Naturvetenskap; Natural sciences;

   Sammanfattning : Photosynthesis is a process in which photons from sunlight excite chlorophylls in the thylakoid membranes of plants, algae and cyanobacteria. The photo-oxidised reaction centre chlorophyll P700 is re-reduced by an electron transferred from the soluble, blue copper protein plastocyanin. LÄS MER

3. 22. Symbiotic and pathogenic factors in plant-microbe interaction: Structural basis of C-glycoside metabolism and lipoprotein transport in bacteria

   Författare :Valentina Furlanetto; Christina Divne; Mats Sandgren; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plant-Bacteria Interaction; Symbiotic Communication; C-Glycosylated Compounds; Enzymatic Deglycosylation; Pathogenic Interactions; Lipoprotein Localization; Lol System; Biotechnology; Bioteknologi;

   Sammanfattning : The communication between plants and bacteria involves a complex chemical signaling network that mediates responses to various biotic and abiotic stresses, as well as establishing symbiotic relationships between different organisms.The first part of the thesis focuses on a mechanism for symbiotic communication between plants and bacteria and more specifically on how C-glycosylated aromatic polyketide compounds produced by plants can be used as a mechanism for plants to communicate with beneficial bacteria.

4. 23. Characterization of c-di-GMP signaling in Salmonella typhimurium

   Författare :Roger Simm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Signal transduction via cyclic nucleotides is a general mechanism utilized by cells from all kingdoms of life. Identification of cyclic diguanosine monophosphate (c-di-GMP) as an allosteric activator of the cellulose synthase in Gluconacetobacter xylinus 20 years ago, paved the way for the discovery of a novel general signalling system which is unique to bacteria.

5. 24. Characterization of Camplyobacter jejuni and C. coli from Swedish patients and chickens - antibiotic resistance, genomic diversity and detection

   Författare :Anna-Clara Rönner; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Campylobacter jejuni is a Gram-negative, non-spore forming bacterium, which is currently the most common pathogen causing reported cases of food poisoning in Sweden, as well as in most other industrialized countries. Eating or drinking something containing these bacteria is often determined to be the source of infection and as few as 500 bacteria can be enough to cause illness. LÄS MER

7. 25. Regulatory mechanisms involved in pathoadaptation of extraintestinal pathogenic Escherichia coli

   Författare :Nikola Zlatkov; Bernt Eric Uhlin; Åke Forsberg; Sun Nyunt Wai; Eliora Ron; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ExPEC; PAIs; pathoadaptation; citrate; metabolism; filamentation; toxins; molekylärbiologi; Molecular Biology; mikrobiologi; Microbiology;

   Sammanfattning : Establishment of commensal bacteria within a new niche of their host usually promotes the transition from commensalism to pathogenicity. Extraintestinal Pathogenic Escherichia coli (ExPEC) represent different pathovars with biphasic lifestyle – they can reside in the gut as commensals or they can escape and cause diseases elsewhere in the human body.
