ID 3.4.24.60 DE dactylysin. AN peptide hormone inactivating endopeptidase. CA Hydrolysis of peptides of at least six residues, with bulky hydrophobic CA residues in the P1' position. Shows a preference for hydrophobic doublets CA such as -Phe-|-Phe- and -Phe-|-Leu- in somatostatin-(1-14)-peptide and CA dynorphin A-(1-6)-peptide, respectively. CC -!- An endopeptidase of 100 kDa secreted from the skin of Xenopus laevis. CC -!- Resembles neprilysin in insensitivity to 1 uM captopril, but differs CC in being insensitive to thiorphan and unable to digest (5-Met)- CC enkephalin, (5-Leu)-enkephalin, oxytocin and substance P-(7-11)- CC peptide. //
