1. Structural and Biochemical Studies of Antibiotic Resistance and Ribosomal Frameshifting
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
2. Frameshifting as a tool in analysis of transfer RNA modification and translation
Sammanfattning : Studies of ribosomal reading frame maintenance are often based on frameshift mutation suppression experiments. In this thesis, suppression of a frameshift mutation in Salmonella enterica serovar Typhimurium by a tRNA and a ribosomal protein are described. LÄS MER
3. Studies on Translation Initiation and Termination in Escherichia coli
Sammanfattning : Translation initiation factor 1 (IF1) has been shown to be an RNA chaperone. In order to find functional interactions that IF1 may have with rRNA, we have isolated second-site suppressors of a cold-sensitive IF1 mutant. LÄS MER
4. Influence of wobble uridine modifications on eukaryotic translation
Sammanfattning : Elongator is a conserved six subunit protein (Elp1p-Elp6p) complex that is required for the formation of ncm5 and mcm5 side chains at wobble uridines in transfer RNAs (tRNAs). Moreover, loss-of-function mutations in any gene encoding an Elongator subunit results in translational defects and a multitude of phenotypic effects. LÄS MER
5. Wobble modifications and other features in transfer RNA important for decoding and reading frame maintenance
Sammanfattning : Transfer RNA (tRNA) is the adaptor molecule responsible for bringing the correct amino acid to the ribosome during protein synthesis. tRNA contains a number of modified nucleosides, which are derivatives of the four normal nucleosides. LÄS MER
