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-Rule MF_01629

Catalytic activity

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

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

Cofactor

Binds 1 FMN per subunit By similarity. HAMAP-Rule MF_01629

Pathway

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

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

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_01629

Sequence similarities

Belongs to the pyridoxamine 5'-phosphate oxidase family.
