3. 17. Enzymes involved in heparan sulfate chain elongation : Function of a novel family of tumor suppressors?

   Författare :Thomas Lind; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; heparan sulfate; biosynthesis; glycosyltransferase; EXT1; EXT2; UDP-glucosedehydrogenase; KfiC; Biokemi; Biochemistry; Biokemi; Medical and Physiological Chemistry; medicinsk och fysiologisk kemi;

   Sammanfattning : Heparan sulfate (HS) is a glycosaminoglycan associated with many physiological functions such as regulation of growth factor action and cell adhesion. The HS polysaccharide is synthesized by alternating addition of D-glucuronic acid (GlcA) and N-acetyl-D-glucosamine (GlcNAc) units from the corresponding UDP-sugar precursors. LÄS MER

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

   Sammanfattning : Translation is a central biological process, that is catalysed by a machinery consisting of RNA and protein. In this thesis three different protein components of the bacterial protein synthesis system have been structurally studied. LÄS MER

7. 20. Accuracy of protein synthesis and its tuning by mRNA modifications

   Författare :Gabriele Indrisiunaite; Måns Ehrenberg; Suparna Sanyal; Jaanus Remme; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Protein synthesis; Translation; Accuracy; Release factor; Termination; mRNA modifications; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Sammanfattning : The ribosome is a large macromolecular complex that synthesizes all proteins in the cell in all kingdoms of life. Proteins perform many vital functions, ranging from catalysis of biochemical reactions to muscle movement. It is essential for cells and organisms that proteins are synthesized rapidly and accurately. LÄS MER
