Pyridoxine/pyridoxamine 5'-phosphate oxidase

Gene

pdxH

Organism
Vibrio cholerae serotype O1 (strain ATCC 39315 / El Tor Inaba N16961)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the oxidation of either pyridoxine 5'-phosphate (PNP) or pyridoxamine 5'-phosphate (PMP) into pyridoxal 5'-phosphate (PLP).UniRule annotation

Catalytic activityi

Pyridoxamine 5'-phosphate + H2O + O2 = pyridoxal 5'-phosphate + NH3 + H2O2.UniRule annotation
Pyridoxine 5'-phosphate + O2 = pyridoxal 5'-phosphate + H2O2.UniRule annotation

Cofactori

FMNUniRule annotationNote: Binds 1 FMN per subunit.UniRule annotation

Pathwayi: pyridoxal 5'-phosphate salvage

This protein is involved in step 1 of the subpathway that synthesizes pyridoxal 5'-phosphate from pyridoxamine 5'-phosphate.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Pyridoxine/pyridoxamine 5'-phosphate oxidase (pdxH)
This subpathway is part of the pathway pyridoxal 5'-phosphate salvage, which is itself part of Cofactor metabolism.
