Comments [?]

Function Catalyzes the oxidation of either pyridoxine 5'-phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP).
Catalytic activity Pyridoxamine 5'-phosphate + H(2)O + O(2) = pyridoxal 5'-phosphate + NH(3) + H(2)O(2).
Pyridoxine 5'-phosphate + O(2) = pyridoxal 5'-phosphate + H(2)O(2).
Cofactor FMN
Note: Binds 1 FMN per subunit.
Pathway Cofactor biosynthesis; B6 vitamer interconversion; pyridoxal 5'-phosphate from pyridoxamine 5'-phosphate; step 1/1.
Cofactor biosynthesis; B6 vitamer interconversion; pyridoxal 5'-phosphate from pyridoxine 5'-phosphate; step 1/1.
Subunit Homodimer.
Similarity Belongs to the pyridoxamine 5'-phosphate oxidase family.
