ENZYME entry: EC 1.14.19.45

Accepted Name
sn-1 oleoyl-lipid 12-desaturase.
Reaction catalysed
A 1-oleoyl-2-acyl-[glycerolipid] + 2 reduced ferredoxin [iron-sulfur] cluster + O(2) + 2 H(+) <=> a 1-linoleoyl-2-acyl-[glycerolipid] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O
Comment(s)
  • The enzyme, characterized from cyanobacteria, introduces a cis double bond at carbon 12 of oleoyl groups (18:1) attached to the sn-1 position of glycerolipids.
  • The enzyme is a methyl-end desaturase, introducing the new double bond between a pre-existing double bond and the methyl-end of the fatty acid.
  • It is nonspecific with respect to the polar head group of the glycerolipid.
