This amino acids 667 to 676 fragment of the amyloid precursor protein (APP) is a beta secretase substrate containing an Mca/ Dap(Dnp) FRET pair. Beside being cleaved by beta-site APP cleavage enzyme (BACE) between the Met and Asp residues, it can also be cleaved by the enzyme thimet oligopeptidase (TOP), Ex/Em=330 nm/390 nm.
