 | Hazard Information | Back Directory |  [Description]
  Suc-Leu-Leu-Val-Tyr-AMC (94367-21-2) is a fluorogenic substrate for the chymotryptic activity of the 20S proteasome1 and other chymotrypsin-like proteases, as well as calpains2. A commonly used substrate for assaying proteasomal enzymatic activity.3,4 Excitation max.: 360 nm; emission max.: 460 nm. |  [Uses]
  Suc-Leu-Leu-Val-Tyr-AMC is a fluorgenic substrate for chymotrypsin-like proteases, as well as calpains. It can be used to treat tuberculosis. |  [Definition]
  ChEBI: A tetrapeptide compound with a succinyl group at the N-terminal and a 7-amino-4-methylcoumarin group at the C-terminal. |  [Biochem/physiol Actions]
  In the presence of chymotrypsin-like enzyme activity, the fluorophore, 7-amido-4-methylcoumarin is released from N-succinyl-Leu-Leu-Val-Tyr-7-amido-4-methylcoumarin. The fluorescence obtained is a measure of the enzyme activity.6 |  [References]
