ENZYME entry: EC 1.14.19.26

Accepted Name
Acyl-[acyl-carrier-protein] 6-desaturase.
Reaction catalysed
Palmitoyl-[acyl-carrier protein] + 2 reduced ferredoxin [iron-sulfur] cluster + O(2) + 2 H(+) <=> (6Z)-hexadec-6-enoyl-[acyl-carrier protein] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O
Comment(s)
  • The enzyme, characterized from the endosperm of the plant Thunbergia alata (black-eyed Susan vine), introduces a cis double bond at carbon 6 of several saturated acyl-[acyl-carrier protein]s.
  • It is most active with palmitoyl-[acyl-carrier protein] (16:0), but can also act on myristoyl-[acyl-carrier protein] (14:0) and stearoyl-[acyl-carrier protein] (18:0).
  • The position of the double bond is determined by its distance from the carboxyl end of the fatty acid.
