ENZYME entry: EC 1.14.19.43
| Accepted Name |
|---|
| palmitoyl-[glycerolipid] 3-(E)-desaturase.
|
| Reaction catalysed |
|---|
| a 1-acyl-2-hexadecanoyl-glycerolipid + 2 H(+) + O2 + 2 reduced [2Fe-2S]-[ferredoxin] <=> a 1-acyl-2-[(3E)-hexadec-3-enoyl]-glycerolipid + 2 H2O + 2 oxidized [2Fe-2S]-[ferredoxin] |
| Comment(s) |
|---|
- The enzyme introduces an unusual trans double bond at carbon 3 of a
palmitoyl group attached to the sn-2 position of glycerolipids.
- The enzyme from the plant Arabidopsis thaliana is specific for
palmitate in phosphatidylglycerol.
- The enzyme from tobacco can also accept oleate and alpha-linolenate
if present at the sn-2 position of phosphatidylglycerol.
