| FUNCTION | Catalyzes the oxidation of either pyridoxine 5'-phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP). |
| CATALYTIC ACTIVITY | Reaction=pyridoxamine 5'-phosphate + O2 + H2O = pyridoxal 5'-phosphate + H2O2 + NH4(+); Xref=Rhea:RHEA:15817, ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:16240, ChEBI:CHEBI:28938, ChEBI:CHEBI:58451, ChEBI:CHEBI:597326; EC=1.4.3.5; |
| CATALYTIC ACTIVITY | Reaction=pyridoxine 5'-phosphate + O2 = pyridoxal 5'-phosphate + H2O2; Xref=Rhea:RHEA:15149, ChEBI:CHEBI:15379, ChEBI:CHEBI:16240, ChEBI:CHEBI:58589, ChEBI:CHEBI:597326; EC=1.4.3.5; |
| COFACTOR | Name=FMN; Xref=ChEBI:CHEBI:58210; Note=Binds 1 FMN per subunit.; |
| PATHWAY | Cofactor metabolism; pyridoxal 5'-phosphate salvage; pyridoxal 5'-phosphate from pyridoxamine 5'-phosphate: step 1/1. |
| PATHWAY | Cofactor metabolism; pyridoxal 5'-phosphate salvage; pyridoxal 5'-phosphate from pyridoxine 5'-phosphate: step 1/1. |
| SUBUNIT | Homodimer. |
| SIMILARITY | Belongs to the pyridoxamine 5'-phosphate oxidase family. |
