General description
Fluorogenic substrate for chymotrypsin-like enzymes, such as cathepsin B and calpain which have been implicated in programmed cell death.
Application
N-succinyl-Leu-Leu-Val-Tyr-7-amido-4-methylcoumarin was used in proteasome chymotrypsin-like activity assay in Jurkat cell lysate6 and crude cell lysate of rice.7
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

Proteasomes are multisubunit proteases that exist universally among eukaryotes. They have multiple proteolytic activities and are believed to have important roles in regulating cell cycle, selective intracellular proteolysis, and antigen presentation. Here we have partially purified Leishmania chagasi proteasome. The
