Function
function
Catalyzes the oxidation of either pyridoxine 5'-phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP).
Catalytic activity
- H2O + O2 + pyridoxamine 5'-phosphate = H2O2 + NH4+ + pyridoxal 5'-phosphate
Cofactor
Note: Binds 1 FMN per subunit.
Pathway
Cofactor metabolism; pyridoxal 5'-phosphate salvage; pyridoxal 5'-phosphate from pyridoxamine 5'-phosphate: step 1/1.
