Subject field(s)
  • Biological Sciences
  • Biotechnology
DEF

General name for a proteolytic enzyme that catalyzes the hydrolysis of terminal peptide linkages in a polypeptide chain, thus releasing free amino acids.

CONT

Tests of various synthetic peptides as substrates showed that ... chymotrypsin ... is an endopeptidase; i.e., it can split certain types of peptide linkages wherever they occur in a peptide chain, in contrast to the exopeptidases, which can split only terminal peptide bonds.

Domaine(s)
  • Sciences biologiques
  • Biotechnologie
DEF

Enzyme protéolytique catalysant la rupture des liaisons peptidiques en détachant un acide aminé terminal. On distingue des aminopeptidases et des carboxypeptidases.

CONT

Chez les Mammifères, la digestion protéique se poursuit au-delà de l'estomac par l'intervention des sécrétions pancréatiques et intestinales. Le suc pancréatique est en effet riche en enzymes protéolytiques : trypsine, chymotrypsine, protaminase et carboxypeptidases. Cette digestion est complétée par des exopeptidases (aminopeptidase, di- et tripeptidases) produites par la muqueuse intestinale.
