Oxidizes pyridoxal to 4-pyridoxolactone, but does not have activity toward pyridoxal 5'-phosphate, pyridoxine, pyridoxamine, pyridoxamine 5'-phosphate, 4-phthalaldehyde, 2-nitrobenzaldehyde, pyridine, formaldehyde, 2-carboxybenzaldehyde or sugars. Publication Abstract from PubMed Pyridoxal 4-dehydrogenase catalyzes the irreversible oxidation of pyridoxal to 4-pyridoxolactone and is involved in degradation pathway I of pyridoxine, a vitamin B(6) compound. Its crystal structure was elucidated for the first time. Molecular replacement with (S)-1-phenylthanol dehydrogenase (PDB code 2EW8) was adopted to determine the tertiary structure of the NAD(+)-bound enzyme.
