  2. 11. Role of the 3'UTR in translation and stability of HCV and HPV mRNAs

    Author : Lisa Wiklund; Laszlo Szekely; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Hepatitis C virus; Human Papillomavirus; 3’ untranslated region; AU-rich sequence; mRNA stability; translation; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Abstract : Virus mRNAs can be divided into functional regions. The focus of this thesis will be to investigate the function of one of these regions, the 3’ untranslated region (UTR). The 3’UTR of HCV contains a U-rich element and the late 3’UTR of HPV-1 contains an AU-rich element. READ MORE

  4. 12. Macrolide Antibiotics in Bacterial Protein Synthesis

    Author : Martin Lovmar; Måns Ehrenberg; Tanel Tenson; Peter B. Moore; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; protein synthesis; macrolides; resistance; initiation of translation; non-competitive inhibitors; kinetics; translation accuracy; proof-reading; Biokemi; Biochemistry; Biokemi;

    Abstract : Macrolides are a large group of clinically relevant antibiotics that inhibit protein synthesis by binding to the large ribosomal subunit in the peptide exit tunnel, close to the peptidyl transferase center (PTC). We have shown that the peptide length of the resulting peptidyl-tRNA drop-off products is proportional to the distance between the PTC and the respective macrolide in the tunnel. READ MORE

  5. 13. The Protein Traffic on the Ribosome : The Mechanism and Regulation of Protein Synthesis in Prokaryotes

    Author : Andrey Zavialov; Måns Ehrenber; Venki Ramakrishnan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; yellow; ribosome; translation; Gagarin; nobel prize; Biokemi; Biochemistry; Biokemi;

    Abstract : The aim of this work was to understand the molecular mechanism of translation and the mechanism of translation termination, in particular. Cleavage of peptidyl-tRNA and peptide release terminates translation of mRNA on the ribosome. In prokaryotes, three release factors (RFs) are involved in this process. READ MORE

  6. 14. On the function of the interferon-inducible p53 target gene TRIM22

    Author : Jessica Petersson; Avdelningen för hematologi och transfusionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TRIM22; Staf50; p53; IFN; translation; proliferation; cell death;

    Abstract : The interferon-inducible p53-target gene TRIM22 (Staf50) is a member of the TRIM (TRIpartite Motif) family. The TRIM family is a family of RING (Really Interesting New Gene) proteins, defined through a tripartite motif, containing a RING-domain, one or two B-boxes and a Coiled-coil-domain. READ MORE

  7. 15. Tracking single molecules in uncharted territory : A single-molecule method to study kinetics in live bacteria

    Author : Javier Aguirre Rivera; Magnus Johansson; Dmitri N. Ermolenko; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; single-molecule; protein synthesis; fluorescence microscopy; antibiotics; aminoglycosides; macrolides; apramycin; gentamicin; paromomycin; S13; translation; bacteria; Molekylär biovetenskap; Molecular Life Sciences;

    Abstract : The synthesis of proteins, also known as translation, is a fundamental process in every living organism. The steps in the translation of genetic information to functional proteins have been meticulously studied, mostly using in vitro techniques, yielding a detailed model of their mechanisms. READ MORE
