1. Then methionine aminopeptidase ( MAP ) removes the residue from the chain. 2. The methionine residue can be further removed by the enzyme methionine aminopeptidase . 3. It does not inhibit arginyl aminopeptidase ( aminopeptidase B ). 4. It does not inhibit arginyl aminopeptidase ( aminopeptidase B ). 5. Aminopeptidase is active in the anterior and posterior midgut regions before and after feeding.6. Oxytocin is known to be metabolized by the oxytocinase, leucyl / cystinyl aminopeptidase . 7. Mature AM is degraded by the aminopeptidase neprilysin. 8. Aminopeptidase N ( CD13 / APN ) is highly expressed on the endothelium of growing vessels.9. One important aminopeptidase is a zinc-dependent enzyme produced and secreted by glands of the small intestine. 10. Some advanced studies have shown a high homology between the Aminopeptidase N and the Angiotensin-converting enzyme.
