  2. 1. Marker genes : molecular tools for in situ monitoring of bacterial distribution and activity in environmental samples

    Author : Annika Unge; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Biokemi;

    Abstract : Many different microorganisms carry out environmental functions, such as nutrient cycling, plant growth enhancement, or biodegradation. Some microorganisms also negatively affect their environment by causing disease. READ MORE

  4. 2. Eukaryotic Ribosome Biogenesis : Focus on the function of the assembly factor Mrd1p

    Author : Åsa Segerstolpe; Lars Wieslander; Susan Gerbi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome biogenesis; nucleolus; pre-rRNA processing; RNA-binding proteins; Mrd1; Molecular Biology; molekylärbiologi;

    Abstract : The ribosome, the protein factory of the cell, is essential for all life forms. The ribosome is a large RNA-protein machine. It is built in a complex, multi-step process that involves a large number of accessory trans-acting factors and the synthesis consumes a considerable part of the cellular energy. READ MORE

  5. 3. High-resolution phenotypic profiling of a eukaryotic ribosome

    Author : Jonathan Esguerra; Göteborgs universitet; []
    Keywords : ribosome; ribosomal protein genes; box C D snoRNA; box H ACA snoRNA; 2’-O-ribose methylation; pseudouridylation; high-resolution phenotypic profiling; chemogenetic profiling; Saccharomyces cerevisiae; rRNA modification;

    Abstract : All living cells contain ribosomes, complex macromolecular assemblies of ribonucleic acid (RNA) and proteins, responsible for synthesizing polypeptides in a process called translation. High-resolution three-dimensional ribosomal structures coupled with biochemical studies have paved the way in understanding the various mechanistic events during protein synthesis. READ MORE

  6. 4. Organization of mitochondrial gene expression in yeast : Specific features of organellar protein synthesis

    Author : Kirsten Kehrein; Martin Ott; Thomas A Fox; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mitochondria; translation; bc1 complex; ribosome; gene expression; Biochemistry; biokemi;

    Abstract : Mitochondria contain their own genetic system, encoding key subunits of the oxidative phosphorylation system. These subunits are expressed by an organelle-specific gene expression machinery. READ MORE

  7. 5. Studies on Translation Initiation and trans-Translation

    Author : Serhiy Surkov; Leif Isaksson; Udo Bläsi; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; E. coli; ribosome; IF1; tmRNA; trans-translaton; Molecular biology; Molekylärbiologi; molekylärgenetik; Molecular Genetics;

    Abstract :  Translation initiation factor 1 (IF1) is an essential bacterial protein, without any clearly defined function in translation initiation. Same point mutants in this protein exhibit cold-sensitivity. In addition, a sequence specific increase in test protein expression has been observed for these mutants. READ MORE
