- 5-nitrosalicylate + O2 2-oxo-3-(5-oxofuran-2-ylidene)propanoate + nitrite (overall reaction)
- (1a) 5-nitrosalicylate + O2 4-nitro-6-oxohepta-2,4-dienedioate
- (1b) 4-nitro-6-oxohepta-2,4-dienedioate 2-oxo-3-(5-oxofuran-2-ylidene)propanoate + nitrite (spontaneous reaction)
The enzyme from soil bacterium Bradyrhizobium sp. JS329 participates in 5-nitroanthranilate degradation.
