Description

Description générale

An internally quenched fluorogenic peptide substrate containing the α-secretase cleavage site of β-Amyloid Precursor Protein (APP). Shown to be a substrate for yapsin 2, a glycosyl-phosphatidylinositol-linked yeast aspartyl protease (V_max/K_m = 0.031 min^-1). The cleavage is shown to occur at the Lys-Leu bond.

An internally quenched fluorogenic peptide substrate that contains the α-secretase cleavage site of β-amyloid precursor protein (APP). Shown to be an effective substrate for yapsin-2, a glycosyl-phosphatidylinositol-linked aspartyl protease found in yeast (V_max/K_m = 0.031 min^-1). The cleavage has been shown to occur at the Lys-Leu bond. Excitation max: ~340 nm; emission max: ~490 nm.
