Protein attributes

Sequence length	350 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Probable lyase that catalyzes an essential reaction in C-terminal alpha-amidation of peptides. Mediates the dismutation of the unstable peptidyl(2-hydroxyglycine) intermediate to glyoxylate and the corresponding desglycine peptide amide. C-terminal amidation of peptides such as neuropeptides is essential for full biological activity By similarity.
Catalytic activity	Peptidylamidoglycolate = peptidyl amide + glyoxylate.
Cofactor	Zinc By similarity.
Subcellular location	Secreted Potential.
Sequence similarities	Belongs to the peptidyl-alpha-hydroxyglycine alpha-amidating lyase family. Contains 4 NHL repeats.
