1.13.11.64 | 5-nitrosalicylate + O2 |
results are consistent with a dioxygenase-catalyzed ring opening followed by spontaneous lactonization and nitrite elimination and enzyme-catalyzed hydrolysis of the lactone to produce maleylpyruvate |
Bradyrhizobium sp. |
2-oxo-3-(5-oxofuran-2-ylidene)propanoate + nitrite |
overall reaction. The initial ring fission product of 5-nitrosalicylate dioxygenation is spontaneously and rapidly cyclized to form lactones, accompanied by the release of NO2- |
