General Information
Term pyridoxamine phosphate oxidase activity ID (Ontology) GO:0004733 (Gene Ontology)
Definition Catalysis of the reaction: pyridoxamine 5'-phosphate + H2O + O2 = pyridoxal 5'-phosphate + NH4+ + H2O2. This activity can also oxidize pyridoxine 5'-phosphate to pyridoxal 5'-phosphate + H2O2.[ EC:1 PubMed:11786019 ]
