ENZYME entry: EC 1.14.14.40

Accepted Name
phenylalanine N-monooxygenase
Alternative Name(s)
CYP79A2
CYP79D16
phenylalanine N-hydroxylase
Reaction catalysed
L-phenylalanine + 2 O2 + 2 reduced [NADPH--hemoprotein reductase] = (E)-phenylacetaldehyde oxime + CO2 + 2 H(+) + 3 H2O + 2 oxidized [NADPH--hemoprotein reductase]
Comment(s)
  • This enzyme, found in plants, catalyzes two successive N-hydroxylations of L-phenylalanine, a committed step in the biosynthesis of benzylglucosinolate and the cyanogenic glucosides (R)-prunasin and (R)-amygdalin.
  • The product of the two hydroxylations, N,N-dihydroxy-L-phenylalanine, is labile and undergoes dehydration followed by decarboxylation, producing an oxime.
  • It is still not known whether the decarboxylation is spontaneous or catalyzed by the enzyme.
  • Formerly EC 1.14.13.124 and EC 1.14.13.n1.
