EC 1.14.19.11

Accepted name: palmitoyl-[acyl-carrier-protein] 4-desaturase

Reaction: palmitoyl-[acyl-carrier protein] + reduced acceptor + O2 = (4Z)-hexadec-4-enoyl-[acyl-carrier protein] + acceptor + 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 enzyme, characterized from the plant Coriandrum sativum (coriander), is involved in biosynthesis of petroselinate [(6Z)-octadec-6-enoate], which is formed by elongation of (4Z)-hexadec-4-enoate.
