Peptide motifs are crucial mediators of protein-protein interactions as well as sites of specific protease activity. The detection and characterization of these events is therefore indispensable for a detailed understanding of cellular regulation. Here, we present versatile and modular sensors that allow the user to detect protease activity and protein-peptide interactions, as well as to screen for inhibitors using chromogenic, fluorescent, or luminescent output.
