ENZYME - 1.14.14.43 (methylsulfanyl)alkanaldoxime N-monooxygenase

Accepted Name
(methylsulfanyl)alkanaldoxime N-monooxygenase
Alternative Name(s)
(methylthio)alkanaldoxime N-monooxygenase
CYP83A1
Reaction catalysed
an (E)-omega-(methylsulfanyl)-alkanal oxime + glutathione + reduced [NADPH--hemoprotein reductase] + O2 = an S-[(1E)-1-(hydroxyimino)-omega-(methylsulfanyl)alkyl]-L-glutathione + oxidized [NADPH--hemoprotein reductase] + 2 H2O + H(+)
Comment(s)
  • Involved in the biosynthesis of glucosinolates in plants.
  • Catalyzes an N-hydroxylation of the E isomer of n-(methylsulfanyl)aldoximes, forming an aci-nitro intermediate that reacts non-enzymically with glutathione to produce an N-alkyl- thiohydroximate adduct, the committed precursor of glucosinolates.
  • In the absence of a thiol compound, the enzyme is suicidal, probably due to interaction of the reactive aci-nitro intermediate with active site residues.
