  1. 1. Insights Into Protein Synthesis - Structural Aspects of Elongation Factor G and Fusidic Acid Inhibition

    Författare :Sebastian Hansson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molekylär biofysik; Structure chemistry; Strukturkemi; Molecular biophysics; Biologi; Biology; Biomedicinska vetenskaper; Biomedical sciences; conformational change; fusidic acid; protein synthesis; elongation factor G; crystal structures;

    Sammanfattning : Elongation factor G (EF-G) catalyses the translocation step in protein synthesis on the ribosome. During this event the antibiotic Fusidic acid (FA) binds to and irreversably inhibits the release of the EF-G:GDP complex from the ribosome. LÄS MER

  2. 2. Structural and Biochemical Studies of Antibiotic Resistance and Ribosomal Frameshifting

    Författare :Yang Chen; Maria Selmer; Dominique Fourmy; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; protein synthesis; elongation; elongation factor G; fusidic acid; antibiotic resistance; aminoglycoside adenyltransferase; ribosomal frameshifting; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Sammanfattning : Protein synthesis, translation, performed by the ribosome, is a fundamental process of life and one of the main targets of antibacterial drugs. This thesis provides structural and biochemical understanding of three aspects of bacterial translation.Elongation factor G (EF-G) is the target for the antibiotic fusidic acid (FA). LÄS MER

  3. 3. Characterizing Elongation of Protein Synthesis and Fusidic Acid Resistance in Bacteria

    Författare :Srihari Nagendra Ravi Kiran Koripella; Suparna Sanyal; Daniel Wilson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Elongation factor-G; FusB; GTP; Staphylococcus aureus; Escherichia coli and Fusidic acid; Molecular Biology; Molekylärbiologi;

    Sammanfattning : Protein synthesis is a highly complex process executed by the ribosome in coordination with mRNA, tRNAs and translational protein factors. Several antibiotics are known to inhibit bacterial protein synthesis by either targeting the ribosome or the proteins factors involved in translation. LÄS MER

  4. 4. Mechanisms and Inhibition of EF-G-dependent Translocation and Recycling of the Bacterial Ribosome

    Författare :Anneli Borg; Måns Ehrenberg; Ruben Gonzalez; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Protein synthesis; Elongation factor G; Translocation; Ribosome recycling; Fusidic acid; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : The GTPase elongation factor G (EF-G) is an important player in the complex process of protein synthesis by bacterial ribosomes. Although extensively studied much remains to be learned about this fascinating protein. LÄS MER

  5. 5. Ribosomal translocation in real time : Method development to Applications

    Författare :Chang-il Kim; Suparna Sanyal; Martin Ott; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ribosome; EF-G; pyrene mRNA; aminoglycoside; ribosomal protein; GTP hydrolysis; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : Translational elongation is the process in which the ribosome adds one amino acid at a time to the nascent peptide chain. As the ribosome elongates the peptide chain by 14 - 20 amino acids per second and performs hundreds of such cycles per protein, ‘elongation’ is one of the most crucial steps in translation. LÄS MER
