Activity

The peptide substrate contains a highly fluorescent 7-methoxycoumarin group that is efficiently quenched by resonance energy transfer to the 2,4-dinitrophenyl group. It can be used to measure the activities of peptidases that are capable of cleaving an amide bond between the fluorescent group and the quencher group, causing an increase in fluorescence.

It is an excellent substrate for caspase-1/interleukin-converting enzyme (ICE) and angiotensin I-converting enzyme-2 (ACE-2) (Enari, M. et al., 1996, Nature 380:723; Vickers, C. et al., 2002, J. Biol. Chem. 277:14838). The cleavage sites by ICE and ACE-2 are the peptide bonds between Ala and Asp and between Pro and Lys, respectively.
