Acting on paired donors, with incorporation or reduction of molecular oxygen;
With oxidation of a pair of donors resulting in the reduction of O2 to two molecules of water
palmitoyl-CoA,ferrocytochrome b5:oxygen oxidoreductase (14,15 cis/trans-dehydrogenating)
The enzyme, found in the moth Ostrinia furnacalis (Asian corn borer), produces a mixture of (E)- and (Z)- isomers. The products are subsequently truncated by partial beta-oxidation to a blend of 12(E/Z)-tetradec-12-enoyl-CoA, which are converted to the species-specific sex pheromones (E)- and (Z)-tetradec-12-enoyl acetates.
