CC   -!- FUNCTION: Catalyzes the oxidation of either pyridoxine 5'-
CC       phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal
CC       5'-phosphate (PLP) (By similarity).
CC   -!- CATALYTIC ACTIVITY: Pyridoxamine 5'-phosphate + H(2)O + O(2) =
CC       pyridoxal 5'-phosphate + NH(3) + H(2)O(2).
CC   -!- CATALYTIC ACTIVITY: Pyridoxine 5'-phosphate + O(2) = pyridoxal 5'-
CC       phosphate + H(2)O(2).
CC   -!- COFACTOR: Binds 1 FMN per subunit (By similarity).
CC   -!- PATHWAY: Cofactor biosynthesis; B6 vitamer interconversion;
CC       pyridoxal 5'-phosphate from pyridoxamine 5'-phosphate: step 1/1.
CC   -!- PATHWAY: Cofactor biosynthesis; B6 vitamer interconversion;
CC       pyridoxal 5'-phosphate from pyridoxine 5'-phosphate: step 1/1.
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- SIMILARITY: Belongs to the pyridoxamine 5'-phosphate oxidase
CC       family.
