exopeptidase

ex·o·pep·ti·dase

E0279600 (ĕk′sō-pĕp′tĭ-dās′, -dāz′)n. 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

Exopeptidase

exopeptidase

[¦ek·sō′pep·tə‚dās] (biochemistry) An enzyme that acts on the terminal peptide bonds of a protein chain.

Exopeptidase

an enzyme of the hydrolase class. Exopeptidases catalyze the splitting of amino acid residues from an amine or carboxyl end of a protein or peptide molecule. The two main kinds are aminopeptidases and carboxypeptidases.

exopeptidase

[ek″so-pep´tĭ-dās] a proteolytic enzyme whose action is limited to terminal peptide linkages.

ex·o·pep·ti·dase

(ek'sō-pep'ti-dās), An enzyme that catalyzes the hydrolysis of the terminal amino acid of a peptide chain; for example, carboxypeptidase. Compare: endopeptidase.

ex·o·pep·ti·dase

(eks'ō-pep'ti-dās) An enzyme that catalyzes the hydrolysis of the terminal amino acid of a peptide chain (e.g., carboxypeptidase).
Compare: endopeptidase

exopeptidase

An enzyme that acts to split off AMINO ACIDS or sometimes dipeptides from the ends of a protein molecule.

exopeptidase

a type of protein-splitting ENZYME that hydrolyses the terminal PEPTIDE BONDS rather than those bonds within the chain. There are three main types of exopeptidase in the mammalian gut, each attacking a particular area of the protein: carboxypeptidase attacks the carboxyl end of the chain; aminopeptidase attacks the amino end of the chain; dipeptidase breaks the bond between DIPEPTIDES. Such enzymes complete the digestion of protein prior to absorption into the blood stream. Compare ENDOPEPTIDASE.
