1. 1. Formation of Thiolated Nucleosides in tRNA in Salmonella enterica serovar typhimurium

   Författare :Hans Lundgren; Glenn Björk; Charles Lauhon; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : tRNA; modified nucleosides; thiolation; sulfur metabolism; Salmonella; Molecular biology; Molekylärbiologi;

   Sammanfattning : The presence and synthesis of transfer RNA (tRNA) is highly conserved in all organisms and a lot of genetic material is dedicated to its synthesis. tRNA contains a large number of modified nucleosides and several diverse functions have been found but much about their function is still unknown.

3. 2. Frameshifting as a tool in analysis of transfer RNA modification and translation

   Författare :Ramune Leipuviene; Glenn Björk; Diana Downs; Umeå universitet; []

   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
