Leucyl-cystinyl aminopeptidase (LNPEP)

Release of an N-terminal amino acid, cleaves before cysteine, leucine as well as other amino acids. Degrades peptide hormones such as oxytocin, vasopressin and angiotensin III, and plays a role in maintaining homeostasis during pregnancy.

May be involved in the inactivation of neuronal peptides from the brain. Cleaves Met-enkephalin and dynorphin.
