Identification
Name:Aminoacyl-histidine dipeptidase
Synonyms:
  • Beta-alanyl-histidine dipeptidase
  • Carnosinase
  • Cysteinylglycinase
  • Peptidase D
  • Xaa-His dipeptidase
  • X-His dipeptidase
Gene Name:pepD
Enzyme Class:
Biological Properties
General Function:Involved in hydrolase activity
Specific Function:Dipeptidase with broad substrate specificity. Requires dipeptide substrates with an unblocked N-terminus and the amino group in the alpha or beta position. Non-protein amino acids and proline are not accepted in the C-terminal position, whereas some dipeptide amides and formyl amino acids are hydrolyzed. Also shows cysteinylglycinase activity, which is sufficient for E.coli to utilize cysteinylglycine as a cysteine source
