EC 1.14.19.32 Details
show Brenda entryEC number
1.14.19.32
Accepted name
palmitoyl-CoA 14-(E/Z)-desaturase
Reaction
(1) palmitoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = (14E)-hexadec-14-enoyl-CoA + 2 ferricytochrome b5 + 2 H2O;;(2) palmitoyl-CoA + 2 ferrocytochrome b5 + O2 + 2 H+ = (14Z)-hexadec-14-enoyl-CoA + 2 ferricytochrome b5 + 2 H2O
Systematic name
palmitoyl-CoA,ferrocytochrome b5:oxygen oxidoreductase (14,15 cis/trans-dehydrogenating)
Comment
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 β-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.
