EC 1.14.19.11 Details
show Brenda entryEC number
1.14.19.11
Accepted name
acyl-[acyl-carrier-protein] 4-desaturase
Reaction
palmitoyl-[acyl-carrier protein] + 2 reduced ferredoxin [iron-sulfur] cluster + O2 + 2 H+ = (4Z)-hexadec-4-enoyl-[acyl-carrier protein] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O
Other name(s)
Δ4-palmitoyl-[acyl carrier protein] desaturase
Systematic name
palmitoyl-[acyl-carrier protein],reduced acceptor:oxygen oxidoreductase (4,5 cis-dehydrogenating)
Comment
The enzymes from the plants Coriandrum sativum (coriander) and Hedera helix (English ivy) are involved in biosynthesis of petroselinate [(6Z)-octadec-6-enoate], which is formed by elongation of (4Z)-hexadec-4-enoate. The ivy enzyme can also act on oleoyl-[acyl-carrier protein] and palmitoleoyl-[acyl-carrier protein], generating the corresponding 4,9-diene.
