  1. 1. Eukaryotic translation initiation : natural and artificial control

    Author : Hans Erik Johansson; Stockholms universitet; []

    Abstract : .... READ MORE

  2. 2. Study on the Function of Translation Initiation Factor IF1

    Author : Victor Croitoru; Leif A. Isaksson; Kim Kusk Mortensen; Stockholms universitet; []
    Keywords : translation; initiation factor IF1; mutagenesis; A-site; RNA chaperone; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Initiation is the first step in protein biosynthesis representing a fundamental event in cell life which determines fidelity, efficiency and regulation of gene expression. In addition to the ribosome and mRNA, three protein factors IF1, IF2 and IF3 are involved in the initiation of translation in prokaryotes. READ MORE

  3. 3. Studies on Translation Initiation and trans-Translation

    Author : Serhiy Surkov; Leif Isaksson; Udo Bläsi; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; E. coli; ribosome; IF1; tmRNA; trans-translaton; Molecular biology; Molekylärbiologi; molekylärgenetik; Molecular Genetics;

    Abstract :  Translation initiation factor 1 (IF1) is an essential bacterial protein, without any clearly defined function in translation initiation. Same point mutants in this protein exhibit cold-sensitivity. In addition, a sequence specific increase in test protein expression has been observed for these mutants. READ MORE

  4. 4. Studies on Translation Initiation and Termination in Escherichia coli

    Author : Georgina Ibrahim Isak; Leif Isaksson; Suparna Sanyal; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Escherichia coli; translation; ribosome; IF1; RF1; kasugamycin; tRNA; molekylärgenetik; Molecular Genetics;

    Abstract : Translation initiation factor 1 (IF1) has been shown to be an RNA chaperone. In order to find functional interactions that IF1 may have with rRNA, we have isolated second-site suppressors of a cold-sensitive IF1 mutant. READ MORE

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

    Author : Qing Zhao; Leif Isaksson; Lars-Göran Öfverstedt; Odd Nygård; Stockholms universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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
