1.14.13.248
Accepted name
L-aspartate N-monooxygenase (nitrosuccinate-forming)
Reaction
L-aspartate + 3 NADPH + 3 H+ + 3 O2 = (2S)- 2-nitrobutanedioate + 3 NADP+ + 4 H2O;;(1a) L-aspartate + NADPH + H+ + O2 = N-hydroxy-L-aspartate + NADP+ + H2O;;(1b) N-hydroxy-L-aspartate + NADPH + H+ + O2 = N,N-dihydroxy-L-aspartate + NADP+ + H2O;;(1c) N,N-dihydroxy-L-aspartate = (2S)-2-nitrosobutanedioate + H2O (spontaneous);;(1d) (2S)-2-nitrosobutanedioate + NADPH + H+ + O2 = (2S)-2-nitrobutanedioate + NADP+ + H2O

Systematic name
L-aspartate,NADPH:oxygen oxidoreductase [(2S)-2-nitrobutanedioate-forming]
Comment
The enzyme, found in some Actinobacteria, is involved in a pathway that forms nitrite, which is subsequently used to generate a diazo group in some secondary metabolites. Requires an FAD cofactor.
