  1. 1. The importance of maturation factors in 30S ribosomal subunit assembly

    University dissertation from Umeå : Umeå universitet, Institutionen för molekylärbiologi

    Author : Stefan Nord; Umeå universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome; 30S; rRNA; RimP; RbfA; C23U; rpsE; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The assembly of the ribosome is a complex process that needs to be highly efficient to support maximum growth. Although the individual subunits of the ribosome can be reconstituted in vitro, such a reaction is inefficient in comparison to the assembly rate in vivo. READ MORE

  2. 2. Structural and Genetic Studies of Translation in Escherichia coli

    University dissertation from Stockholm : Institutionen för genetik, mikrobiologi och toxikologi

    Author : Qing Zhao; Stockholms universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; electron tomography; ribosome; 30S subunit; 50S subunit; rifampicin; Escherichia coli; Translation initiation; Initiation codon; Downstream Region DR ; MEDICINE Microbiology; immunology; infectious diseases; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar;

    Abstract : Ribosomes are the universal ribonucleoprotein organelles that translate the genetic message from mRNA to protein. In prokaryotes, the ribosomal subunits are 30S and 50S subunit, which bind together during the translation process forming 70S ribosome. READ MORE

  3. 3. Studies on the functional interaction of translation initiation factor IF1 with ribosomal RNA

    University dissertation from Stockholm : Department of Genetics, Microbiology and Toxicology, Stockholm University

    Author : Jaroslav Belotserkovsky; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; ribosome; rRNA mutation; molekylärgenetik; Molecular Genetics;

    Abstract : Translation initiation factor IF1 is a small, essential and ubiquitous protein factor encoded by a single infA gene in bacteria. Although several important functions have been attributed to IF1, the precise reason for its indispensability is yet to be defined. READ MORE

  4. 4. Accessory factors for ribosomal assembly

    University dissertation from Umeå : Molekylärbiologi (Teknisk-naturvetenskaplig fakultet)

    Author : Mattias Lövgren; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; RimM; RbfA; RlmB; ribosomal assembly; rRNA processing; Molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : The assembly of ribosomal RNA (rRNA) and ribosomal proteins (r-proteins) into ribosomal subunits (30S and 50S) is a complex process. Transcription of rRNA requires antitermination proteins and the primary transcripts are processed by ribonucleases. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Christina Tobin; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; MEDICINE Microbiology; immunology; infectious diseases Microbiology; MEDICIN Mikrobiologi; immunologi; infektionssjukdomar Mikrobiologi; NATURAL SCIENCES Chemistry Biochemistry; NATURVETENSKAP Kemi 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
