EC number

1.14.14.30

Accepted name

isobutylamine N-monooxygenase

Reaction

(1) 2-methylpropan-1-amine + FADH₂ + O₂ = N-(2-methylpropyl)hydroxylamine + FAD + H₂O;;(2) 2-methylpropan-1-amine + FMNH₂ + O₂ = N-(2-methylpropyl)hydroxylamine + FMN + H₂O

Other name(s)

vlmH (gene name)

Systematic name

2-methylpropan-1-amine,FADH₂:O₂ N-oxidoreductase

Comment

The enzyme, characterized from the bacterium Streptomyces viridifaciens, is part of a two component system that also includes a flavin reductase, which provides reduced flavin mononucleotide for this enzyme. The enzyme, which is involved in the biosynthesis of the azoxy antibiotic valanimycin, has a similar activity with either FMNH₂ or FADH₂. It exhibits broad specificity, and also accepts propan-1-amine, butan-1-amine, butan-2-amine and benzylamine.
