General description

Proline p-nitroanilide (P-pNA) is a colorimetric substrate for prolyl aminopeptidase (proline iminopeptidase), an enzyme that releases proline from the N-terminus of small peptides.

Application

L-Proline p-nitroanilide trifluoroacetate salt has also been used as a monopeptide substrate for measuring the amidolytic activity of fibrillated peptide catalyst, PC4.
Proline p-nitroanilide (P-pNA) has been used as a substrate for prolyl aminopeptidase (proline iminopeptidase) from cabbage leaves.
