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

    Author : Stefan Nord; Mikael Wikström; Dan Andersson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome; 30S; rRNA; RimP; RbfA; C23U; rpsE; Molecular biology; 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

    Author : Qing Zhao; Leif Isaksson; Lars-Göran Öfverstedt; Odd Nygård; Stockholms universitet; []
    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 ; Microbiology; immunology; infectious diseases; 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

    Author : Jaroslav Belotserkovsky; Leif Isaksson; Diarmaid Hughes; Stockholms universitet; []
    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

    Author : Mattias Lövgren; Mikael Wikström; Dan Andersson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; RimM; RbfA; RlmB; ribosomal assembly; rRNA processing; Molekylärbiologi; Molecular biology; 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

    Author : Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
    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; 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
