ENZYME entry: EC 1.14.19.34
Accepted Name |
Acyl-lipid (9+3)-(E)-desaturase.
|
Alternative Name(s) |
Acyl-lipid 12-(E)-desaturase. |
Reaction catalysed |
- An oleoyl-[glycerolipid] + 2 ferrocytochrome b5 + O(2) + 2 H(+) <=> a (9Z,12E)-octadeca-9,12-dienoyl-[glycerolipid] + 2 ferricytochrome b5 + 2 H(2)O
- A palmitoleoyl-[glycerolipid] + 2 ferrocytochrome b5 + O(2) + 2 H(+) <=> a (9Z,12E)-hexadeca-9,12-dienoyl-[glycerolipid] + 2 ferricytochrome b5 + 2 H(2)O
|
Comment(s) |
- The enzymes from the plants Dimorphotheca sinuata (African daisy) and
Vernicia fordii (tung oil tree) insert a trans double bond in
position C-12 of oleate and palmitoleate incorporated into
glycerolipids.
- The enzyme introduces the new double bond at a position three carbons
away from an existing double bond at position 9, toward the methyl
end of the fatty acid.
- The enzyme from tung oil tree also possesses the activity of
EC 1.14.19.33.
