The ability to characterize entire classes of proteins based on activity would greatly accelerate both the assignment of protein function in the genome era and the identification of new biomarl A large fraction of human enzymes remain uncharacterized in terms of their function in health and disease. We have developed advanced chemical technologies to functionally characterize enzymes directly in native biological systems. The goal of this application is to further develop and apply these technologies to identify enzymes that play important roles in cancer, which may serve as valuable new biomarkers and therapeutic targets.Public Health Relevance
