General annotation (Comments)

Function

Carboxypeptidase which converts angiotensin I to angiotensin 1-9, a peptide of unknown function, and angiotensin II to angiotensin 1-7, a vasodilator. Also able to hydrolyze apelin-13 and dynorphin-13 with high efficiency. May be an important regulator of heart function By similarity. Functional receptor for human coronavirus SARS.

Cofactor

Binds 1 zinc ion per subunit By similarity.

Binds 1 chloride ion per subunit By similarity.

Subunit structure

Interacts with SARS-CoV S protein.

Subcellular location

Processed angiotensin-converting enzyme 2: SecretedBy similarity.

Cell membrane; Single-pass type I membrane proteinBy similarity.

Sequence similarities

Belongs to the peptidase M2 family.
