ID 1.14.12.24 DE 2,4-dinitrotoluene dioxygenase. CA 2,4-dinitrotoluene + NADH + O2 = 4-methyl-5-nitrocatechol + NAD(+) + CA nitrite. CC -!- This enzyme, characterized from the bacterium Burkholderia sp. strain CC DNT, is a member of the naphthalene family of bacterial Rieske non- CC heme iron dioxygenases. CC -!- It comprises a multicomponent system, containing a Rieske [2Fe-2S] CC ferredoxin, an NADH-dependent flavoprotein reductase (EC 1.18.1.3), CC and an alpha3beta3 oxygenase. CC -!- The enzyme forms a cis-dihydroxylated product that spontaneously CC rearranges to form a catechol with accompanying release of nitrite. CC -!- It does not act on nitrobenzene. cf. EC 1.14.12.23. DR Q45695, DNTAC_BURSR; //
