Accepted name: peptidylamidoglycolate lyase
Reaction: [peptide]-(2S)-2-hydroxyglycine = [peptide]-amide + glyoxylate
Other name(s): α-hydroxyglycine amidating dealkylase; peptidyl-α-hydroxyglycine α-amidating lyase; HGAD; PGL; PAL; peptidylamidoglycolate peptidylamide-lyase
Systematic name: [peptide]-(2S)-2-hydroxyglycine peptidyl-amide-lyase (glyoxylate-forming)
Comments: Requires zinc. The enzyme acts on the product of the reaction catalysed by EC peptidylglycine monooxygenase, thus removing a terminal glycine residue and leaving a des-glycine peptide amide. In mammals, the two activities are part of a bifunctional protein.
