Application

L-Leucine-7-amido-4-methylcoumarin hydrochloride (Leu-AMC) as a substrate analog to determine leucine aminopeptidase activity
L-Leucine-7-amido-4-methylcoumarin hydrochloride has been used:
  • as a substrate in fluorescence-based soil assays
  • to determine leucine aminopeptidase activity of both Plasmodium falciparum M1 (PfA-M1) and PfA-M17 enzymes

General description

L-Leucine-7-amido-4-methylcoumarin hydrochloride (Leu-AMC) is a fluorogenic peptidyl substrate for leucine aminopeptidase, an extracellular enzyme found abundantly in natural aquatic systems. This enzyme is one of the various enzymes used by bacteria for protein hydrolysis.
