1.7.3.1 | ethylnitronate + O2 + FMNH2 = acetaldehyde + nitrite + FMN + H2O |
Asp402 acts as the active site base of the enzyme, mechanism: catalysis is initiated by the active site base Asp402 that deprotonates the neutral substrate to yield a carbanion that can attack the N-5 position of the oxidized flavin, CH-bond cleavage is rate limiting for the reduction of the enzyme by nitroethane |

mechanism |
639229 |
1.7.3.1 | ethylnitronate + O2 + FMNH2 = acetaldehyde + nitrite + FMN + H2O |
mechanism, involves removal of a proton from the nitroalkane, forming a carbanion which adds to the N5 of the flavin, elimination of nitrite from the resulting adduct forms an electrophilic imine intermediate which can be attacked by hydroxide |
