EC boosts European electron microscopy research

Fig.: From two-dimensional (2D) crystals to membrane protein structure: The procedure to obtain high-resolution structural information from 2D crystals of membrane proteins is a multi-step process. Upon succesfull growth of 2D crystals, they are analyzed in imaging and diffraction mode using a high-resolution electron microscope. After digitization, sophisticated image processing is required to extract the crystallographic information from the collected data. Finally, interpretation of the reconstructed density yields a three dimensional model, whose quality depends on the success of all preceeding steps.

The 3D-EM Network of Excellence brings together the leading scientists in electron microscopy (EM) from seven European countries. The specialists for the various EM-technologies electron tomography, single particle analysis, and electron crystallography will combine their expertise to reach a very ambitious goal: the three-dimensional (3D) imaging of macromolecules and molecular machines at atomic resolution, with the prospect of a 3D imaging of cell organelles and whole cells.

The determination of the 3D structure of macromolecules (as e.g. proteins), of their interactions and their localisation in cells is essential for the understanding of complex biological processes. It is of particular interest to biotechnological and biomedical companies in the development of novel pharmaceuticals. Recognizing the emerging demand for this type of "Structural Genomics" research, the European Commission has opened opportunities for funding within its Sixth' Research Framework Programme.

The 3D-EM Network of Excellence will provide a platform to integrate and coordinate the efforts of individual European research groups in the EM field. The collaborative activities of the Network will foster innovation and the spreading of novel technology and methodology in the individual partner laboratories. A close cooperation of the 3D-EM Network with the European Microscopy Society (EMS) will support the dissemination of information on these innovations throughout the EM community.

In the five years to come, activities in the 3D-EM consortium will focus on:

(1) The development of a high level training programme in structural biology. The training activities will be established in close collaboration with the European Molecular Biology Lab, Heidelberg (EMBL), the organizer of the renowned series of high level "EMBO-courses". Training courses and workshops will be offered in various areas, including cryo electron microscopy, electron tomography, bio computing, and image processing. They will be instrumental in the dissemination of state-of-the-art methodology in the EM field to the research community.

(2) The foundation of an EM structural database. It will serve as the standard repository for EM structures and provide the essential basis for a comparability of data and their facilitated exchange. Standard data formats and validation standards will be developed according to the demands of the 3D-EM consortium in close collaboration with existing structural databases in the EU and USA.

(3) The creation of a user-friendly software platform. Novel, standardised protocols for structural analysis will be elaborated in a joint effort of the research community and manufacturers. They will enhance the throughput and reduce the requirement for specialist-skills in structural analysis. The public dissemination of novel standard procedures through 3D-EM ultimately will allow state-of-the-art structural research to be performed all over Europe.

The 3D-EM Network of Excellence officially started operating on March 1, 2004. The project was kicked-off during a meeting at the Max-Planck Institute of Biochemistry, Martinsried, end of March 2004.
