It has been 25 years since the first demonstration that frozen hydrated specimens could be used to study the structure of labile biological macromolecules using the electron microscope. This Symposium will examine the present state of the field and its future directions. In the past 25 years, the technique has been applied to 3-D imaging of specimens ranging in size from single protein molecules to large macromolecular complexes including viruses, helical filaments and 2-D and 3-D crystals. The impact of cryoelectron microscopy on biology will be surveyed by authorities in the field who have pioneered this technique. Recent advances in the structural and functional organization of molecular motors, cytoskeleton, ribosomes, viruses and membranes will be discussed by distinguished leaders and younger investigators who are opening new frontiers in cryoelectron microscopy.

In the session on molecular motors and the cytoskeleton, analysis of conformational substates in microtubule and actin associated motors, as well as actin complexed with specific binding proteins will be presented. The high resolution structure of tubulin, which will be described, is a dramatic recent achievement in electron crystallography. The session on single particles will explore application of new techniques, including tomography, to determine the structure and interactions of ribosomes, mitochondrial membrane proteins, and icosahedrally symmetric virus particles. Images of ribosomes at 15Å resolution complexes with tRNA are providing insights into mechanisms of protein synthesis, and the 7Å resolution achieved with complex icosahedral viruses that have not been crystallized is illuminating higher levels of viral organization. The cryomicroscopy of two-dimensional crystals, in particular assemblies of membrane proteins, has been a major success story. In this session, new structural analyses nearing completion will be reported and prospects of further advances in 2-D electron crystallography will be discussed.
