| Accepted name: | juglone 3-hydroxylase | ||
| Reaction: | 2 juglone + O2 = 2 3,5-dihydroxy-1,4-naphthoquinone (overall reaction) (1a) 2 juglone + 2 H2O = 2 naphthalene-1,2,4,8-tetrol (1b) 2 naphthalene-1,2,4,8-tetrol + O2 = 2 3,5-dihydroxy-1,4-naphthoquinone + 2 H2O |

| Glossary: | juglone = 5-hydroxy-1,4-naphthoquinone | ||
| Other name(s): | juglone hydroxylase; naphthoquinone hydroxylase; naphthoquinone-hydroxylase | ||
| Systematic name: | 5-hydroxy-1,4-naphthoquinone,water:oxygen oxidoreductase (3-hydroxylating) | ||
| Comments: | Even though oxygen is consumed, molecular oxygen is not incorporated into the product. Catalysis starts by incorporation of an oxygen atom from a water molecule into the substrate. The naphthalene-1,2,4,8-tetrol intermediate is then oxidized by molecular oxygen, which is reduced to water. Also acts on 1,4-naphthoquinone, naphthazarin and 2-chloro-1,4-naphthoquinone. | ||
