oyster-peptide-powder Dipeptidyl peptidase 3 (DPP3), also known as DPP III or Dipeptidyl Peptidase 3 / DPP3, is a fascinating enzyme that plays a significant and increasingly recognized role in various physiological and pathological processes.DPP3 As a zinc-dependent aminopeptidase and a member of the M49 family of metallopeptidases, DPP3 is characterized by its ability to cleave and degrade bioactive peptides. This intricate enzymatic activity underpins its involvement in critical bodily functions, including blood pressure regulation, cellular responses, and even as a potential biomarker for certain medical conditions.

The Enzymatic Prowess of Dipeptidyl Peptidase 3

At its core, DPP3 functions as a metallo-exopeptidase that cleaves a dipeptide from the unsubstituted amino end of its substrates. This means it precisely removes two amino acids from the beginning of various peptide chains, effectively altering their biological activity. Research indicates that dipeptidyl peptidase 3 is adept at hydrolyzing peptides ranging from 3 to 10 amino acids in length, and some studies suggest it can degrade oligopeptides with 4 to 12 amino acid residuesMechanisms of beneficial effects of DPP-4 inhibitors as a promising .... This broad substrate specificity allows DPP3 to influence a variety of signaling pathways作者：LJ Donato·2025—Dipeptidyl peptidase 3 (DPP3) is a peptidase released from dying cells.

A key area of action for dipeptidyl peptidase 3 is the renin-angiotensin pathway. It is known to cleave and degrade bioactive peptides within this system, including angiotensin, a potent vasoconstrictorEntry - *606818 - DIPEPTIDYL PEPTIDASE III; DPP3. By modulating angiotensin levels, DPP3 plays a role in regulating blood pressure. This has led to the exploration of DPP III in the context of hypertension, with some research suggesting a novel therapeutic role for dipeptidyl peptidase III in the treatment of hypertension and its protective effects on hypertension-sensitive organsDipeptidyl peptidase 3 - Mus musculus (Mouse) | UniProtKB. Conversely, it has been found to act as a myocardial depressant factor, highlighting its complex influence on cardiovascular function.
