5-nitrosalicylate dioxygenase
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 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)
