5-nitrosalicylate dioxygenase (EC 1.13.11.64, naaB (gene)) is an enzyme with systematic name 5-nitrosalicylate:oxygen 1,2-oxidoreductase (decyclizing).[1][2] This enzyme catalyses the following chemical reaction

5-nitrosalicylate + O2 [math]\displaystyle{ \rightleftharpoons }[/math] 2-oxo-3-(5-oxofuran-2-ylidene)propanoate + nitrite (overall reaction)
(1a) 5-nitrosalicylate + O2 [math]\displaystyle{ \rightleftharpoons }[/math] 4-nitro-6-oxohepta-2,4-dienedioate
(1b) 4-nitro-6-oxohepta-2,4-dienedioate [math]\displaystyle{ \rightleftharpoons }[/math] 2-oxo-3-(5-oxofuran-2-ylidene)propanoate + nitrite (spontaneous reaction)

The enzyme from soil bacterium Bradyrhizobium sp. JS329 participates in 5-nitroanthranilate degradation.
