| Comment(s) |
|---|
- The enzyme, characterized from the bacteria Pseudomonas sp. MA-1 and
Mesorhizobium loti, participates in the degradation of pyridoxine
(vitamin B(6)).
- Although the enzyme was initially thought to be a dioxygenase,
oxygen-tracer experiments have shown that it is a monooxygnase,
incorporating only one oxygen atom from molecular oxygen.
- The second oxygen atom that is incorporated into the product
originates from a water molecule, which is regenerated during the
reaction and thus does not show up in the reaction equation.
- Formerly EC 1.14.12.4.
