The 3 substrates of this enzyme are pyridoxal, H₂O, and O₂, whereas its product is 4-pyridoxate.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with oxygen as acceptor. The systematic name of this enzyme class is pyridoxal:oxygen 4-oxidoreductase. This enzyme participates in vitamin B₆ metabolism. It employs one cofactor, molybdenum.
