EC | 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) | ||||||||||||
Comments: | 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. | ||||||||||||

Systematic name: | (Z)-hexadec-9-enoyl-[acyl-carrier protein]:malonyl-[acyl-carrier protein] C-acyltransferase (decarboxylating) | ||||||||||||
Comments: | Involved in the dissociated (or type II) fatty acid biosynthesis system that occurs in plants and bacteria. While the substrate specificity of this enzyme is very similar to that of EC 2.3.1.41, β-ketoacyl-[acyl-carrier-protein] synthase I, it differs in that palmitoleoyl-[acyl-carrier protein] is not a good substrate of EC 2.3.1.41 but is an excellent substrate of this enzyme [1,2]. The fatty-acid composition of Escherichia coli changes as a function of growth temperature, with the proportion of unsaturated fatty acids increasing with lower growth temperature. This enzyme controls the temperature-dependent regulation of fatty-acid composition, with mutants lacking this acivity being deficient in the elongation of palmitoleate to cis-vaccenate at low temperatures [3,4]. | ||||||||||||
