DE   5-pyridoxate monooxygenase.
AN   5-pyridoxate dioxygenase.
AN   5-pyridoxate oxidase.
CA   5-pyridoxate + NADPH + O2 = 2-(acetamidomethylene)-3-
CA   (hydroxymethyl)succinate + NADP(+).
CC   -!- The enzyme, characterized from the bacterium Arthrobacter sp Cr-7,
CC       participates in the degradation of pyridoxine (vitamin B6).
CC   -!- Although the enzyme was initially thought to be a dioxygenase,
CC       oxygen-tracer experiments have suggested that it is a monooxygnase,
CC       incorporating only one oxygen atom from molecular oxygen into the
CC       product.
CC   -!- The second oxygen atom originates from a water molecule, which is
CC       regenerated during the reaction and thus does not show up in the
CC       reaction equation.
CC   -!- Formerly EC 1.14.12.5.
