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,NADPH:oxygen oxidoreductase

Comments: A heme-thiolate protein (cytochrome P-450). The enzyme, found in insects except for Lepidoptera (moths and butterflies) is specific for methyl farnesoate (cf. EC, farnesoate epoxidase) [1,2].
