Cofactor
| Cofactor | Comment | Organism | Structure |
|---|---|---|---|
| 1-deaza-FAD | when 1-deaza-FAD is used as cofactor, the enzyme carries out each step in catalysis except the transfer of oxygen to 4-hydroxybenzoate | Pseudomonas aeruginosa | |
| 6-Hydroxy-FAD | when 6-hydroxy-FAD is used as cofactor, the enzyme has a lower turnover rate than the native enzyme | Pseudomonas aeruginosa | |
| FAD | contains 1 mol of FAD per subunit | Pseudomonas aeruginosa | |
