Thioamide-Based Fluorescent Protease Sensors

Abstract

Thioamide quenchers can be paired with compact fluorophores to design "turn-on" fluorescent protease substrates. We have used this method to study a variety of serine-, cysteine-, carboxyl-, and metallo-proteases, including trypsin, chymotrypsin, pepsin, thermolysin, papain, and calpain. Since thioamides quench some fluorophores red-shifted from those… (More)
