ENZYME entry: EC

Accepted Name
sn-1 acyl-lipid omega-3 desaturase (ferredoxin).
Reaction catalysed
  • a 1-[(6Z,9Z,12Z)-octadectrienoyl]-2-acyl-glycerolipid + 2 H(+) + O2 + 2 reduced [2Fe-2S]-[ferredoxin] <=> a 1-[(6Z,9Z,12Z,15Z)-octadectetraenoyl]-2-acyl-glycerolipid + 2 H2O + 2 oxidized [2Fe-2S]-[ferredoxin]
  • a 1-[(9Z,12Z)-octadecdienoyl]-2-acyl-glycerolipid + 2 H(+) + O2 + 2 reduced [2Fe-2S]-[ferredoxin] <=> a 1-[(9Z,12Z,15Z)-octadectrienoyl]-2-acyl-glycerolipid + 2 H2O + 2 oxidized [2Fe-2S]-[ferredoxin]
  • The enzyme, characterized from cyanobacteria, introduces a cis double bond at carbon 15 of linoleoyl and gamma-linolenoyl groups attached to the sn-1 position of glycerolipids.
  • The enzyme is an omega desaturase, and determines the location of the double bond by counting three carbons from the methyl end of the fatty acid.
  • It is non-specific with respect to the polar head group of the glycerolipid.
