Activity‐Based Fingerprinting of Proteases

Not inhibited. We have successfully synthesized and tested a panel of activity-based small-molecule probes that target different classes of proteases on the basis of their enzymatic activities and substrate specificities rather than their inhibition. We have demonstrated that these probes are useful for generating unique substrate fingerprint profiles of proteases in gel-based proteomic experiments. Preliminary results indicate that they might be equally amenable for microarray-based enzyme profiling experiments.
