EC 1.13.11.32 Details
EC number
1.13.11.32
Accepted name
2-nitropropane dioxygenase
Reaction
2 2-nitropropane + O2 = 2 acetone + 2 nitrite
Systematic name
2-nitropropane:oxygen 2-oxidoreductase
CAS registry number
61584-55-2
Comment
While the enzyme from the fungus Neurospora crassa contains non-covalently bound FMN as the cofactor, that from the yeast Williopsis mrakii contains FAD [2]. This enzyme differs from EC 1.7.3.1, nitroalkane oxidase, in that the preferred substrates are anionic nitronates rather than neutral nitroalkanes [2,3]. The enzyme has broad substrate specificity that is independent of substrate size [2,3]. Some other nitroalkanes, including nitroethane, 1-nitropropane and 3-nitropentan-2-ol, can act as donors, but more slowly.
