ENZYME entry: EC 1.14.19.47
Accepted Name |
Acyl-lipid (9-3)-desaturase.
|
Alternative Name(s) |
Acyl-lipid 6-desaturase. |
Acyl-lipid Delta(6)-desaturase. |
Delta(6)-desaturase. |
Reaction catalysed |
- An alpha-linolenoyl-[glycerolipid] + 2 ferrocytochrome b5 + O(2) + 2 H(+) <=> a stearidonoyl-[glycerolipid] + ferricytochrome b5 + 2 H(2)O
- A linoleoyl-[glycerolipid] + 2 ferrocytochrome b5 + O(2) + 2 H(+) <=> a gamma-linolenoyl-[glycerolipid] + ferricytochrome b5 + 2 H(2)O
|
Comment(s) |
- The enzyme, characterized from the moss Physcomitrella patens and the
plant Borago officinalis (borage), introduces a cis double bond at
carbon 6 of several acyl-lipids that contain an existing Delta(9) cis
double bond.
- The enzyme contains a cytochrome b5 domain that acts as the electron
donor for the active site of the desaturase.
