ENZYME entry: EC 1.14.19.46

Accepted Name
sn-1 linoleoyl-lipid 6-desaturase.
Reaction catalysed
a 1-[(9Z,12Z)-octadecdienoyl]-2-acyl-glycerolipid + 2 H(+) + O2 + 2 reduced [2Fe-2S]-[ferredoxin] <=> a 1-[(6Z,9Z,12Z)-octadectrienoyl]-2-acyl-glycerolipid + 2 H2O + 2 oxidized [2Fe-2S]-[ferredoxin]
Comment(s)
  • 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 non-specific with respect to the polar head group of the glycerolipid.
