    Sammanfattning : This thesis focuses on understanding the underlying molecular mechanisms of infectious diseases, which claim nearly 9 million lives annually. The research centers on critical analysis of pathogen mechanisms and drug resistance. I have mainly focused on two clades of pathogens: Enterococcus faecalis and microsporidia. E. LÄS MER

  4. 3. Rational and combinatorial genetic engineering approaches for improved recombinant protein production and purification

    Författare :Nina Bandmann; Per-Åke Nygren; Helena Berglund; KTH; []

    Sammanfattning : The bacterium Escherichia coli (E. coli) is in many situations an ideal host for production of recombinant proteins, since it generally provides a rapid and economical means to achieve sufficiently high product quantities. LÄS MER

  5. 4. Intracellular Flows and Fluctuations

    Författare :Johan Elf; Måns Ehrenberg; Peter Wolynes; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; mesoscopic; reaction-diffusion; protein synthesis; amino acid; flow; fluctuations; Molekylärbiologi; Molecular biology; Molekylärbiologi; Molecular Biotechnology; Molekylär bioteknik;

    Sammanfattning : Mathematical models are now gaining in importance for descriptions of biological processes. In this thesis, such models have been used to identify and analyze principles that govern bacterial protein synthesis under amino acid limitation. LÄS MER

  7. 5. Biomolecular simulations, from RNA to protein : thermodynamic and dynamic aspects

    Författare :Olof Allnér; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The process of transforming the information stored in the DNA of genes into functional RNA molecules and proteins via transcription and translation is the most fundamental process of all known life. Even though these processes involve large macromolecules and dynamics on long time scales they all ultimately rely on atomic level interactions between nucleic acids or amino acids. LÄS MER
