phenylalanine N-monooxygenase EC#: 1.14.14.40; ChemWhat Code: 1375548

Product Name phenylalanine N-monooxygenase
Example Structure Example Structure of phenylalanine N-monooxygenase EC#: 1.14.14.40
Synonyms CYP79A1, CYP79A2, CYP79D16, cytochrome P450 79D16
EC Number 1.14.14.40
CAS Registry Number
Comments This cytochrome P-450 (heme-thiolate) enzyme, found in plants, catalyses 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 catalysed by the enzyme.
Cofactor heme-thiolate
History
Reactions L-phenylalanine + 2 [reduced NADPH–hemoprotein reductase] + 2 O(2) = (E)-phenylacetaldoxime + 2 [oxidized NADPH–hemoprotein reductase] + CO(2) + 3 H(2)O.
