Peptidyl-dipeptidase B

Peptidyl-dipeptidase B (, dipeptidyl carboxyhydrolase, atriopeptin convertase, atrial di-(tri)peptidyl carboxyhydrolase, peptidyldipeptidase B, atrial dipeptidyl carboxyhydrolase, atrial peptide convertase) is an enzyme. It catalyses the following chemical reaction


 * Release of a C-terminal dipeptide or exceptionally a tripeptide

This membrane-bound, zinc metallopeptidase is located in mammalian atrial myocytes.
