EC 3.4.24.71

Accepted name: endothelin-converting enzyme 1

Reaction: Hydrolysis of the -Trp21Val- bond in big endothelin to form endothelin 1

Other name(s): endothelin-converting enzyme; ECE-1

Comments: A phosphoramidon-sensitive metalloendopeptidase in peptidase family M13 (neprilysin family). An integral membrane protein predominantly of endothelial cells, which generates the potent vasoconstrictor endothelin 1 from its inactive precursor
