ENZYME entry: EC 1.14.12.24

Accepted Name
2,4-dinitrotoluene dioxygenase.
Reaction catalysed
2,4-dinitrotoluene + NADH + O(2) <=> 4-methyl-5-nitrocatechol + nitrite + NAD(+)
Comment(s)
  • This enzyme, characterized from the bacterium Burkholderia sp. strain DNT, is a member of the naphthalene family of bacterial Rieske non- heme iron dioxygenases.
  • It comprises a multicomponent system, containing a Rieske [2Fe-2S] ferredoxin, an NADH-dependent flavoprotein reductase (EC 1.18.1.3), and an alpha-3-beta-3 oxygenase.
  • The enzyme forms a cis-dihydroxylated product that spontaneously rearranges to form a catechol with accompanying release of nitrite.
  • It does not act on nitrobenzene.
  • Cf. EC 1.14.12.23.
