General annotation (Comments)

Function

Catalyzes the oxidation of either pyridoxine 5'-phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP) By similarity. HAMAP MF_01629

Catalytic activity

Pyridoxamine 5'-phosphate + H2O + O2 = pyridoxal 5'-phosphate + NH3 + H2O2. HAMAP MF_01629

Pyridoxine 5'-phosphate + O2 = pyridoxal 5'-phosphate + H2O2. HAMAP MF_01629

Cofactor

Binds 1 FMN per subunit By similarity. HAMAP MF_01629

Pathway

Cofactor biosynthesis; B6 vitamer interconversion; pyridoxal 5'-phosphate from pyridoxamine 5'-phosphate: step 1/1. HAMAP MF_01629
