This volume provides a broad coverage of enzyme targets for therapeutic intervention and emerging assay technologies for key enzyme classes in pharmaceutical research. In addition to new developments in proteomics, this volume includes two emerging technologies in Life Sciences: metabolomics (including glycomics and lipidomics) and preclinomics. The ultimate goal in pharmaceutical and biotechnology research is to develop drugs to meet un-met medical needs. These in-depth discussions provide researchers and graduate students an important source of reference in the biotechnology and pharmaceutical research.In summary, this volume overviews assay technologies for essential enzyme classes in drug discovery, recent developments in metabolomics , proteomics and preclinomics, and new enzyme targets for therapeutic intervention.
