Summary

Description
May be involved in the metabolism of insect hormones and in the breakdown of synthetic insecticides.
Catalyzes the conversion of methyl farnesoate to juvenile hormone III acid (methyl (2E,6E)-(10R)-10,11-epoxy-3,7,11-trimethyl-2,6-dodecadienoate) in juvenile hormone biosynthesis.
Catalytic Activity
methyl (2E,6E)-farnesoate + O2 + reduced [NADPH--hemoprotein reductase] = H(+) + H2O + juvenile hormone III + oxidized [NADPH--hemoprotein reductase]
Cofactor
heme
Biophysicochemical Properties
380 uM for methyl (2E,6E)-farnesoate (with purified enzyme)
26 uM for methyl (2E,6E)-farnesoate (with recombinant enzyme expressed in E.coli)
Miscellaneous
The enzyme is present in all insects, except in lepidoptera (moths and butterflies), and is specific for methyl farnesoate. Lepidoptera contain the farnesoate epoxidase, which is specific for farnesoate.
Similarity
Belongs to the cytochrome P450 family.
