Gathering together a number of experts in the world, the 27th Jerusalem Symposium was devoted to the theme of the modelling of biomolecular structures and mechanisms. As a result of recent growth in both importance and audience, the papers contained in this volume present an evaluation of the status of the present knowledge in this field. The main topics covered by this year's Symposium include nucleic acids and their interactions, proteins and their interaction, membranes and their interactions, enzymatic processes and the pharmacological and medical aspects of these subjects. Readers should benefit from the interdisciplinary approach which provides coverage of both theoretical and experimental advances.
