1. 1. Ribosomal RNA Modification Enzymes : Structural and functional studies of two methyltransferases for 23S rRNA modification in Escherichia coli

   Författare :Avinash S. Punekar; Maria Selmer; Martino Bolognesi; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; ribosome biogenesis; ribosome assembly; ribosomal RNA; peptidyltransferase center; domain V; post-transcriptional modification; methyltransferases; S-adenosyl-methionine; RlmM; Cm2498; RlmJ; m6A2030; X-ray crystallography; substrate recognition; substrate specificity; catalytic mechanism; evolution; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biokemi; Biochemistry;

   Sammanfattning : Escherichia coli ribosomal RNA (rRNA) is post-transcriptionally modified by site-specific enzymes. The role of most modifications is not known and little is known about how these enzymes recognize their target substrates. LÄS MER

3. 2. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA

   Författare :Gunnar Alkemar; Odd Nygård; Anders Virtanen; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eukaryotes; expansion segment; ribosomes; rRNA; secondary structure; structure of rRNA.; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

   Sammanfattning : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. LÄS MER

4. 3. Non-protein-coding RNA : Transcription and regulation of ribosomal RNA

   Författare :Stefanie Böhm; Ann-Kristin Östlund Farrants; Brian McStay; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ribosomal RNA; non-coding RNA; ribosomal genes; rDNA gene; B-WICH; chromatin remodelling; histone modification; Cell Biology; cellbiologi;

   Sammanfattning : Cell growth and proliferation are processes in the cell that must be tightly regulated. Transcription of ribosomal RNA and ribosomal biogenesis are directly linked to cell growth and proliferation, since the ribosomal RNA encodes for the majority of transcription in a cell and ribosomal biogenesis influences directly the number of proteins that are synthesized.

5. 4. Ribosomal RNA dynamics studied by NMR-spectroscopy

   Författare :Hampus Karlsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The ribosome is a large macromolecular machine that consists of both ribosomal proteins and ribosomal RNA (rRNA). It is a complex consisting of two subunits held together by non-covalent interactions, intersubunit bridges and some of these bridging interactions are mediated by the rRNA. LÄS MER
