This volume is the first to combine latest information on viral, microbial and cellular proteolytic enzymes as potential targets for human therapeutics. Proteases control a large array of physiological reactions, and are involved in a variety of pathological processes for which effective medications are currently needed and/or being sought after. Although protease inhibitors have been investigated for many years, few have been employed therapeutically. Recent break- through by HIV protease inhibitors as therapeutic drugs has re-encouraged the search for inhibitors of other proteolytic...
