1. The cell cycle of the hyperthermophilic archaeal genus Sulfolobus
Abstract : 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).

2. Transcription regulation and growth phase transition in hyperthermoacidophilic archaea
Abstract : 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. READ MORE

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

4. On the stability of proteins from hyperthermophiles : a structural and thermodynamic study
Abstract : 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. READ MORE

5. Electron crystallography of soluble proteins
Abstract : 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. READ MORE
