ID 1.13.12.16 DE nitronate monooxygenase. AN 2-nitropropane dioxygenase. AN 2-NPD. AN nitroalkane oxidase. AN NMO. CA ethylnitronate + O2 = acetaldehyde + chemical entity + H(+) + nitrite. CC -!- Previously classified as EC 1.13.11.32, but it is now recognized that CC this was the result of the slow ionization of nitroalkanes to their CC nitronate (anionic) forms. CC -!- The enzymes from the fungus Neurospora crassa and the yeast CC Williopsis saturnus var. mrakii (formerly classified as Hansenula CC mrakii) contain non-covalently bound FMN as the cofactor. CC -!- Neither hydrogen peroxide nor superoxide were detected during enzyme CC turnover. CC -!- Active toward linear alkyl nitronates of lengths between 2 and 6 CC carbon atoms and, with lower activity, toward propyl-2-nitronate. CC -!- The enzyme from N. crassa can also utilize neutral nitroalkanes, CC but with lower activity. CC -!- Formerly EC 1.13.11.32. DR P47177, 2NDP_YEAST ; Q12723, 2NPD_CYBMR ; Q01284, 2NPD_NEUCR ; //
