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.

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.

Prolyl aminopeptidases are specific exopeptidases that catalyze the hydrolysis of the N-terminus proline residue of peptides and proteins. In the present study, the prolyl aminopeptidase gene (pap) from Aspergillus oryzae JN-412 was optimized through the codon usage of Pichia pastoris.

Aminopeptidase, preferring phenylalanine-p-nitroanilide as substrate, and proline iminopeptidase, highly-specific for proline-p-nitroanilide, were isolated from cabbage leaves (Brassica oleraceae var. capitata). As pH optima, 7.2-7.5 for aminopeptidase activity and 8.0-8.5 for proline iminopeptidase were determined. Both peptidases were strongly inhibited by
