ID 1.14.13.166 DE 4-nitrocatechol 4-monooxygenase. CA 4-nitrocatechol + NAD(P)H + O(2) = 2-hydroxy-1,4-benzoquinone + nitrite + CA NAD(P)(+) + H(2)O. CF FAD. CC -!- The enzyme catalyzes the oxidation of 4-nitrocatechol with the CC concomitant removal of the nitro group as nitrite. CC -!- Forms a two-component system with a flavoprotein reductase. CC -!- The enzymes from the bacteria Lysinibacillus sphaericus JS905 and CC Rhodococcus sp. strain PN1 were shown to also catalyze EC 1.14.13.29, CC while the enzyme from Pseudomonas sp. WBC-3 was shown to also CC catalyze EC 1.14.13.167. DR Q6F4M8, NPCA_RHOOP ; Q6F4M9, NPCB_RHOOP ; //
