Enkephalinase

Enkephalinases are enzymes that degrade endogenous enkephalin opioid peptides. They include:


 * Aminopeptidase N (APN)
 * Neutral endopeptidase (NEP)
 * Dipeptidyl peptidase 3 (DPP3)
 * Carboxypeptidase A6 (CPA6)
 * Leucyl/cystinyl aminopeptidase (LNPEP)
 * Angiotensin-converting enzyme (ACE)
