Fluorogenic substrate for several matrix metalloproteinases (MMPs). It is cleaved by MMP-1 (kcat/Km=3.3x10M-1s-1), MMP-2 (kcat/Km=5.8×10), MMP-3 (kcat/Km=2.2×10), MMP-7 (kcat/Km=1.2×10), MMP-8, MMP-9 (kcat/Km=6.9×10), and MMP-26 (kcat/Km=4.9×10) Ex/Em=280nm/346nm, although 283/350,360 are also appropriate. Fluorescence at 346 nm by tryptophan occurs once cleavage separates it from the quenching aromatic Dnp moiety. MMPs cleave this peptide between Gly-Leu.
