Description
Z-LLE-AMC is a fluorogenic substrate for the caspase-like post-glutamate peptide hydrolase of the 26S proteasome or 20S proteolytic core. Caspase-like activity can be quantified by fluorescent detection of free AMC (also known as 7-amino-4-methylcoumarin), which is excited at 340-360 nm and emits at 440-460 nm. Z-LLE-AMC is typically used in cell lysates after experimental treatment.
Uses
A fluorogenic substrate for the peptidylglutamyl-peptide hydrolysing (caspase-like) activity of the proteasome which may be stimulated in the presence of Mg2+ ions and rapidly inactivated by N-acetylimidazole
Uses
Z-Leu-Leu-Glu-7-amido-4-methylcoumarin has been used as a fluorogenic substrate for peptidyl glutamyl peptide hydrolase (PGPH) in rat soleus muscle, neonatal cardiomyocytes and rat brain samples.
General Description
Z-Leu-Leu-Glu-7-amido-4-methylcoumarin is a fluoropeptide. It acts as a substrate for caspase-like activity.
Biochem/physiol Actions
Fluorogenic substrate for the measurement of the peptidylglutamyl-peptide hydrolyzing activity of the 20S proteasome.
