ID 1.13.11.64 DE 5-nitrosalicylate dioxygenase. CA 5-nitrosalicylate + O2 = 2-oxo-3-(5-oxofuran-2-ylidene)propanoate + H(+) CA + nitrite. CC -!- The enzyme, characterized from the soil bacterium Bradyrhizobium sp. CC JS329, is involved in the pathway of 5-nitroanthranilate degradation. CC -!- It is unusual in being able to catalyze the ring fission without the CC requirement for prior removal of the nitro group. CC -!- The product undergoes spontaneous lactonization, with concurrent CC elimination of the nitro group. DR D3WZ86, NAAB_BRASZ ; //
