homomethionine N-monooxygenase EC#: 1.14.14.42; ChemWhat Code: 1375550
Product Name | homomethionine N-monooxygenase |
Example Structure | |
Synonyms | CYP79F1, CYP79F2, dihomomethionine N-hydroxylase, hexahomomethionine N-hydroxylase |
EC Number | 1.14.14.42 |
CAS Registry Number | |
Comments | This plant cytochrome P-450 (heme thiolate) enzyme is involved in methionine-derived aliphatic glucosinolates biosynthesis. It catalyses two successive N-hydroxylations, which are followed by dehydration and decarboxylation. CYP79F1 from Arabidopsis thaliana can metabolize homo-, di-, tri-, tetra-, penta-, and hexahomomethionine to their corresponding aldoximes, while CYP79F2 from the same plant can only metabolize penta- and hexahomomethionine. |
Cofactor | heme-thiolate |
History | |
Reactions | An L-polyhomomethionine + 2 O(2) + 2 [reduced NADPH–hemoprotein reductase] = an omega-(methylthio)-(E)-alkanal oxime + CO(2) + 3 H(2)O + 2 [oxidized NADPH–hemoprotein reductase]. |
