1.13.12.16 | ethylnitronate + O2 = acetaldehyde + nitrite + other products |
catalytic and kinetic reaction mechanism, comparison to the nitroalkane oxigenase, EC 1.7.3.1, and other flavin-dependent enzymes, ionization of nitroethane and ethylnitronate in aqueous solution, overview. Enzymatic turnover begins with the rapid equilibrium association of ethylnitronate and the enzyme. In the oxidative pathway, the transfer of a single electron oxidizes the organic substrate and reduces the enzyme-bound flavin to an anionic semiquinone species, the electron transfer occurs while the substrate radical is still bound in the active site of the enzyme. After formation of the flavosemiquinone species in the active site of NMO, the subsequent oxidation of the one electron reduced flavin occurs when molecular oxygen reacts with the anionic flavosemiquinone to yield an enzyme-associated superoxide species, with second-order rate constants |
