General annotation (Comments)

Function

Bifunctional enzyme that catalyzes 2 sequential steps in C-terminal alpha-amidation of peptides. The monooxygenase part produces an unstable peptidyl(2-hydroxyglycine) intermediate that is dismutated to glyoxylate and the corresponding desglycine peptide amide by the lyase part. C-terminal amidation of peptides such as neuropeptides is essential for full biological activity.

Catalytic activity

Peptidylglycine + ascorbate + O2 = peptidyl(2-hydroxyglycine) + dehydroascorbate + H2O.

Peptidylamidoglycolate = peptidyl amide + glyoxylate.

Cofactor

Zinc; for the lyase reaction. Ref.3

Binds 2 copper ions per subunit; For the monoxygenase reaction. Ref.3

Enzyme regulation

Inhibited by EDTA, phenylglyoxal and diethyl pyrocarbonate. Ref.3

Subunit structure

Monomer. Interacts with RASSF9 By similarity.

Subcellular location

Isoform 1: Membrane; Single-pass type I membrane protein.

Isoform 2: Membrane; Single-pass type I membrane protein.

Isoform 3: Secreted. Note: Secreted from secretory granules.

Isoform 4: Secreted. Note: Secreted from secretory granules.

Sequence similarities

In the C-terminal section; belongs to the peptidyl-alpha-hydroxyglycine alpha-amidating lyase family.
