  2. 1. Ribosomes and subunits from Escherichia coli studied by asymmetrical flow field-flow fractionation

    Author : Mikael Nilsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; metabolic engineering; VHb; Vitreoscilla hemoglobin; E. coli; Escherichia coli; separation; subunits; ribosomes; Asymmetrical flow field-flow fractionation; flow FFF; optimization; biotechnological production; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis asymmetrical flow field-flow fractionation (FFF) separations of ribosomes and subunits have been studied. Ribosomal material was prepared from Escherichia coli (E. coli) cells and analyzed by the size separation technique. READ MORE

  4. 2. Ribosome Associated Factors Recruited for Protein Export and Folding

    Author : Amanda Raine; Jarl Wikberg; Harris Bernstein; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Signal recognition particle; trigger factor; ribosomes; protein folding; membrane targeting; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Abstract : Protein folding and export to the membrane are crucial events in the cell. Both processes may be initiated already at the ribosome, assisted by factors that bind to the polypeptide as it emerges from the ribosome. READ MORE

  5. 3. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA

    Author : Gunnar Alkemar; Odd Nygård; Anders Virtanen; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eukaryotes; expansion segment; ribosomes; rRNA; secondary structure; structure of rRNA.; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Abstract : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. READ MORE

  6. 4. Mechanism and Regulation of Initiation of Protein Synthesis in Eubacteria

    Author : Ayman Antoun; Måns Ehrenberg; John Hershey; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Initiation; Protein Synthesis; Initiation Factors; Light Scattering; Ribosomes; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Initiation of protein synthesis in E.coli involves several steps, which lead to the formation of the first peptide bond. This process requires three initiation factors: IF1, IF2 and IF3. READ MORE

  7. 5. Asymmetrical Flow Field-Flow Fractionation in the Application to Biological Macromolecules

    Author : Cecilia Arfvidsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Bioteknik; Biotechnology; biotechnology; recombinant protein production; molecular weight; Escherichia coli; ribosomes; glutenin; asymmetrical flow field-flow fractionation; multiangle light scattering;

    Abstract : Asymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. READ MORE
