This activity can also oxidize pyridoxine 5'-phosphate to pyridoxal 5'-phosphate + H2O2. Reactome:R-HSA-965019 PMP oxidase activity pyridoxine (pyridoxamine)phosphate oxidase activity oxidoreductase activity, acting on the CH-NH2 group of donors, oxygen as acceptor pyridoxal 5'-phosphate biosynthetic process
