CC -!- FUNCTION: Catalyzes the oxidation of either pyridoxine 5'-phosphate
CC (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate
CC (PLP). {ECO:0000255|HAMAP-Rule:MF_01629}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O2 + pyridoxamine 5'-phosphate = H2O2 + NH4(+) +

CC Note=Binds 1 FMN per subunit. {ECO:0000255|HAMAP-Rule:MF_01629};
CC -!- PATHWAY: Cofactor metabolism; pyridoxal 5'-phosphate salvage; pyridoxal
CC 5'-phosphate from pyridoxamine 5'-phosphate: step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_01629}.
