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.

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

Fungi are capable of degrading proteins in their environment by secreting peptidases. However, the link between extracellular digestion and intracellular proteolysis has scarcely been investigated. Mycelial lysates of the filamentous fungus Talaromyces emersonii were screened for intracellular peptidase production. Five
