ENZYME entry: EC 1.14.19.75

Accepted Name
Very-long-chain acyl-lipid omega-9 desaturase.
Reaction catalysed
  • 1-hexacosanoyl-2-acyl-(phosphoglycerolipid) + 2 ferrocytochrome b5 + O(2) + 2 H(+) <=> 1-((17Z)-hexacos-17-enoyl)-2-acyl-(phosphoglycerolipid) + 2 ferricytochrome b5 + 2 H(2)O
  • 1-tetracosanoyl-2-acyl-(phosphoglycerolipid) + 2 ferrocytochrome b5 + O(2) + 2 H(+) <=> 1-((15Z)-tetracos-15-enoyl)-2-acyl-(phosphoglycerolipid) + 2 ferricytochrome b5 + 2 H(2)O
Comment(s)
  • The enzyme, characterized from the plant Arabidopsis thaliana, acts on both 24:0 and 26:0 fatty acids, introducing a cis double bond at a position 9 carbons from the methyl end.
  • These very-long-chain fatty acids are found as a minor component of seed lipids, but also in the membrane phosphatidylethanolamine and phosphatidylserine, in sphingolipids, as precursors and components of cuticular and epicuticular waxes, and in suberin.
