General description

Z-Phe-Arg 7-amido-4-methylcoumarin (Z-FR-AMC) is a peptidomimetic substrate for papainand other enzymes such as cathepsin K. It is also a fluorogenic synthetic peptide for the enzymes cathepsins L and B.

Application

Z-Phe-Arg 7-amido-4-methylcoumarin hydrochloride has been used:
  • as a fluorogenic substrate in actinidin inhibition assay
  • as a kallikrein substrate
  • as a trypsin substrate for fluorometric assay
  • as a cathepsin-L substrate

Biochem/physiol Actions

Z-Phe-Arg 7-amido-4-methylcoumarin (Z-FR-AMC) proteolytic lysis by proteases leads to the liberation of AMC resulting in increased fluorescence in the enzymatic reaction.

Substrates

A fluorogenic substrate for plasma kallikrein.

A previously described "major acidic proteinase" of adult Schistosoma mansoni, believed to play a key role in the parasite's metabolism, has been identified as a cathepsin B (Sm31). Purified Sm cathepsin B was not recognized by anti-Sm32 or anti-cathepsin L

The limited availability of highly selective cathepsin substrates seriously impairs studies designed to monitor individual cathepsin activities in biological samples. Among mammalian cysteine proteases, cathepsin K has a unique preference for a proline residue at P2, the primary determinant of

The effects of peptide proteinase inhibitors on globin hydrolysis by cultured malaria parasites were studied. All of the four cysteine proteinase inhibitors evaluated blocked globin hydrolysis, as documented by the development of a morphological abnormality in which parasite food vacuoles

Within the lysosomal cysteine protease family, cathepsin B is unique due to its ability to act both as an endopeptidase and a peptidyldipeptidase. This latter capacity to remove C-terminal dipeptides has been attributed to the presence of a 20-residue insertion

To identify functionally essential sequences and residues of CTLA-2alpha, in vitro mutagenesis was carried out. The coefficient of inhibition (K(i)) was determined towards rabbit cathepsin L using Z-Phe-Arg-MCA as the substrate. Recombinant CTLA-2alpha inhibited the enzyme potently (K(i) = 15
