  1. 1. Removal and Replacement of Ribosomal Proteins : Effects on Bacterial Fitness and Ribosome Function

    Author : Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; Microbiology; Mikrobiologi; Biochemistry; Biokemi; Mikrobiologi; Microbiology;

    Abstract : Protein synthesis is a complex process performed by sophisticated cellular particles known as ribosomes. Although RNA constitutes the major structural and functional component, ribosomes from all kingdoms contain an extensive array of proteins with largely undefined functional roles. READ MORE

  2. 2. Ribosomal Proteins in Diamond-Blackfan Anemia : Insights into Failure of Ribosome Function

    Author : Jitendra Badhai; Niklas Dahl; Anthony Wright; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diamond-Blackfan anemia; RPS19; Ribosomal proteins; Haploinsufficiency; cell cycle; Apoptosis; Erythropoiesis; Medical genetics; Medicinsk genetik; Clinical Genetics; klinisk genetik;

    Abstract : Diamond-Blackfan anemia (DBA) is a severe congenital anemia characterized by a defect in red blood cell production. The disease is associated with growth retardation, malformations, a predisposition for malignant disease and heterozygous mutations in either of the ribosomal protein (RP) genes RPS7, RPS17, RPS19, RPS24, RPL5, RPL11 and RPL35a.

  3. 3. Ribosomal proteins L5 and L15 : Functional characterisation of important features, in vivo

    Author : Ivailo Simoff; Odd Nygård; Gustavo Nader; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; cellbiologi; Cellbiology;

    Abstract : Protein synthesis is a highly regulated and energy consuming process, during which a large ribonucleoprotein particle called the ribosome, synthesizes new proteins. The eukaryotic ribosome consists of two unequal subunits called: small and large subunits. Both subunits are composed of ribosomal RNA (rRNA) and ribosomal proteins (r-proteins). READ MORE

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

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

    Abstract : 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. 5. Structure determination of ribosomal proteins and development of new methods in biomolecular NMR

    Author : Magnus Helgstrand; KTH; []
    Keywords : nuclear magnetic resonance; structure determination; ribosomal proteins; NMR simulations; NMR theory; NMR assignment software; semiautomatic assignment;

    Abstract : This thesis concerns different areas of biomolecular nuclearmagnetic resonance spectroscopy (NMR). In the first part of thethesis a new formalism for simulations of NMR pulse sequencesis introduced. The formalism is derived both from classicalmechanics and quantum mechanics and is presented forhomonuclear and heteronuclear spin systems. READ MORE
