Amino Acid Sequence

N-Suc-Leu-Leu-Val-Tyr-7-AMC

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

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Substrates

Fluorogenic substrate for chymotrypsin-like enzymes, such as cathepsin B and calpain which have been implicated in programmed cell death.
