EC 1.14.14.127     
Accepted name: methyl farnesoate epoxidase
Reaction: methyl (2E,6E)-farnesoate + [reduced NADPH—hemoprotein reductase] + O2 = juvenile hormone III + [oxidized NADPH—hemoprotein reductase] + H2O

Glossary: juvenile hormone III = methyl (2E,6E,10R)-10,11-epoxy-3,7,11-trimethyldodeca-2,6-dienoate
Other name(s): CYP15A1
Systematic name: methyl (2E,6E)-farnesoate,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase
