A vast number of biochemical reactions are catalysed by molecules fixed to the surface of membranes (or other biological structures) with molecules in the surrounding solution. The study of the mechanisms at these "Biointerfaces" are becoming increasingly important for the understanding of biological catalysts, such as enzymes. This project is the first book to deal with the physical and chemical principles of an emerging field of science, for which the authors have set the ground-work. * The first book to deal with this newly emerging area. * Concentrates on the chemical and physical foundation of enzyme catalysis * Key area for the deeper understanding of biocatalytic processes * Examples for proteins and nucleic acids, two central areas of biochemical and bioorganic research
