  1. 1. The cell cycle of the hyperthermophilic archaeal genus Sulfolobus

    Författare :Karin Hjort; Patrick Dennis; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; Cell cycle; Sulfolobus; Archaea; Origin; Replication; SIRV2; Mikrobiologi; Microbiology; immunology; infectious diseases; Mikrobiologi; immunologi; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : The third domain of life, Archaea is one of the three main evolutionary lineages together with the Bacteria and the Eukarya domains. The archaea are, despite their prokaryotic cell organisation, more closely related to eukaryotes than to bacteria in terms of the informational pathways (DNA replication, transcription and translation).

  3. 2. Transcription regulation and growth phase transition in hyperthermoacidophilic archaea

    Författare :Kun Wang; Ann-Christin Lindås; Finn Werner; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Archaea; Sulfolobus; Transcription regulation; Lrp; TetR; BarR; ChIP-seq; RNA-seq; Transcriptome; growth phase transition; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Organisms from the domain Archaea are ubiquitously represented on our planet and encompass diverse fascinating organisms. The genus Sulfolobus belonging to the phylum Crenarchaeota including hyperthermoacidophilic strains that grow optimally at 65-85°C and pH 2-3. LÄS MER

  4. 3. From Time-Averaged to Time-Resolved Crystallography: Studies on Superoxide Dismutase and Myoglobin

    Författare :Thomas Ursby; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superoxide dismutase; Bayesian statistics; electron difference maps; synchrotron; docking site; photolysis; myoglobin; Time-resolved crystallography; Laue; thermostability; Sulfolobus solfataricus; Molecular biophysics; Molekylär biofysik;

    Sammanfattning : We have studied protein motions with nanosecond time-resolved crystallography. The release of carbon monoxide from its complex with myoglobin (MbCO) was triggered by nanosecond laser pulses. X-ray data were collected with time delays ranging from 4 ns to 1.9 ms using the Laue method, at the European Synchrotron Radiation Facility in Grenoble. LÄS MER

  5. 4. On the stability of proteins from hyperthermophiles : a structural and thermodynamic study

    Författare :Stefan Knapp; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Protein stability; hyperthermophiles; X-ray crystallography; glutamate dehydrogenase; Sso7d.;

    Sammanfattning : In this study the structural and thermodynamic basis of the thermal stability of proteins has been studied using proteins from hyperthermophilic organisms as model systems. A new type of chaperonin (TF55) has been isolated from the hyperthermophilic archaeon Sulfolobus solfataricus consisting of two different subunits named TF55-alpha and TF55-beta. LÄS MER

  7. 5. Electron crystallography of soluble proteins

    Författare :Matthew James Ellis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Interfacial crystallization; electron microscopy; image processing; soluble protein; phospholipid layer;

    Sammanfattning : Protein structures at moderate to high resolution can now be readily solved using an electron microscope and image processing techniques. The averaging conditions required to overcome the low signal to noise ratio of electron microscope images are particularly well satisfied by two-dimensional crystals. LÄS MER
