5-nitrosalicylate dioxygenase

Template:Short description Template:Infobox enzyme 5-nitrosalicylate dioxygenase (Template:EC number, naaB (gene)) is an enzyme with systematic name 5-nitrosalicylate:oxygen 1,2-oxidoreductase (decyclizing). This enzyme catalyses the following chemical reaction

5-nitrosalicylate + O₂ $\rightleftharpoons$ 2-oxo-3-(5-oxofuran-2-ylidene)propanoate + nitrite (overall reaction)

(1a) 5-nitrosalicylate + O₂ $\rightleftharpoons$ 4-nitro-6-oxohepta-2,4-dienedioate

(1b) 4-nitro-6-oxohepta-2,4-dienedioate $\rightleftharpoons$ 2-oxo-3-(5-oxofuran-2-ylidene)propanoate + nitrite (spontaneous reaction)

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