Any of a group of enzymes that catalyze the hydrolysis of single amino acids from the end of a polypeptide chain.

exopeptidase

(ˌɛksəʊˈpɛptɪˌdeɪz)
n
(Biochemistry) any proteolytic enzyme, such as erepsin, that acts on the terminal bonds in a peptide chain. Compare endopeptidase

CatB is considered a major lysosomal cysteine protease for the degradation of collagen in soft connective tissues, as it possesses both endopeptidase and exopeptidase activity which differs from other lysosomal cysteine proteases [44].
The presence of intestinal serine proteases in Oemona hirta Fabricius (Cerambycidae), also was supported by proteolytic assays using a general substrate and specific chemical inhibitors, which showed that only serine protease inhibitors had effect on total proteolytic activity; the predominant endopeptidase activity was attributed to trypsin and chymotrypsin-like proteases while, exopeptidase was related to leucine aminopeptidase.
A sequence-specific exopeptidase activity test (SSEAT) for "functional" biomarker discovery.
Flavourzyme that is an exopeptidase, produced the lowest amount of peptide with small molecular size (15.
Flavorpro[TM] 937MDP is an exopeptidase preparation with low levels of endopeptidase activity.
Glutalytic contains both endopeptidases and exopeptidases to create the correct endopeptidase cleavage pattern near the long chain amino acids that need to be hydrolyzed by the exopeptidase, producing rapid degradation of gluten.
Exopeptidases have also been shown to play an important role in petal senescence and the levels of exopeptidase and endopeptidase activities have been found to be developmentally regulated (Mahagamasekera & David, 2001).
Bitterness in cheese occurs when there is an imbalance of the production of bitter peptides by protease and endopeptidase enzymes, and involves their removal by exopeptidase enzymes.
It was only later revealed that most serum peptides sort into nested sets of sequences, generated by exopeptidase activities superimposed on the proteolytic events of the ex vivo coagulation and complement degradation pathways (3), thus explaining the erratic measurements when preanalytical conditions are not exceedingly well controlled.
This enzyme is an exopeptidase with endopeptidase and glutaminase side activities.
