ENZYME entry: EC

Accepted Name
sn-1 linoleoyl-lipid 6-desaturase.
Reaction catalysed
A 1-linoleoyl-2-acyl-[glycerolipid] + 2 reduced ferredoxin [iron-sulfur] cluster + O(2) + 2 H(+) <=> a 1-gamma-linolenoyl-2-acyl-[glycerolipid] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O
  • The enzyme, characterized from cyanobacteria, introduces a cis double bond at carbon 6 of linoleoyl groups (18:2) attached to the sn-1 position of glycerolipids.
  • The enzyme is a front-end desaturase, introducing the new double bond between a pre-existing double bond and the carboxyl-end of the fatty acid.
  • It is nonspecific with respect to the polar head group of the glycerolipid.
