| Accepted name: | very-long-chain acyl-lipid ω-9 desaturase | ||||
| Reaction: | (1) 1-hexacosanoyl-2-acyl-[phosphoglycerolipid] + 2 ferrocytochrome b5 + O2 + 2 H+ = 1-[(17Z)-hexacos-17-enoyl]-2-acyl-[phosphoglycerolipid] + 2 ferricytochrome b5 + 2 H2O (2) 1-tetracosanoyl-2-acyl-[phosphoglycerolipid] + 2 ferrocytochrome b5 + O2 + 2 H+ = 1-[(15Z)-tetracos-15-enoyl]-2-acyl-[phosphoglycerolipid] + 2 ferricytochrome b5 + 2 H2O |

| Other name(s): | ADS2 (gene name) | ||||
| Systematic name: | very-long-chain acyl-[glycerolipid],ferrocytochrome b5:oxygen oxidoreductase (ω9,ω8-cis-dehydrogenating) | ||||
| Comments: | 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. | ||||
