Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 (FS-6) is a fluorescent peptide that is a quenched MMP peptide substrate. Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 can be used for real-time quantification of MMP enzymatic activity. Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH2 is an elongated peptide of MMP substrate (FS-1) and is active against collagenases (MMP-1, MMP-8, MMP-13 ) and MT1-MMP with higher specificity constants than FS-1[1]. (Ex/Em=325 nm/400 nm)
Specificity of Mca-Lys-Pro-Leu-Gly-Leu-Dap(Dnp)-Ala-Arg-NH26 for collagenases (MMP-1, MMP-8, MMP-13) and MT1-MMP (MMP-14) The constant (kcat/Km) increases by a factor of 2-9, or 3 times than FS-1[1].
