The function of Ensembl gene identifier ENSG00000196549 (MME, membrane metalloendopeptidase) is as follows. Thermolysin-like specificity, but is almost confined on acting on polypeptides of up to 30 amino acids (PubMed:15283675, PubMed:6208535, PubMed:6349683, PubMed:8168535). Biologically important in the destruction of opioid peptides such as Met- and Leu-enkephalins by cleavage of a Gly-Phe bond (PubMed:17101991, PubMed:6349683). Catalyzes cleavage of bradykinin, substance P and neurotensin peptides (PubMed:6208535). Able to cleave angiotensin-1, angiotensin-2 and angiotensin 1-9 (PubMed:15283675, PubMed:6349683). Involved in the degradation of atrial natriuretic factor (ANF) and brain natriuretic factor (BNP(1-32)) (PubMed:16254193, PubMed:2531377, PubMed:2972276). Displays UV-inducible elastase activity toward skin preelastic and elastic fibers (PubMed:20876573). {ECO:0000269|PubMed:15283675, ECO:0000269|PubMed:17101991, ECO:0000269|PubMed:20876573, ECO:0000269|PubMed:2531377, ECO:0000269|PubMed:27588448, ECO:0000269|PubMed:2972276, ECO:0000269|PubMed:6208535, ECO:0000269|PubMed:6349683}.
