ENZYME

ENZYME entry: EC 1.14.19.43

Accepted Name

Palmitoyl-[glycerolipid] 3-(E)-desaturase.

Reaction catalysed

A 1-acyl-2-palmitoyl-[glycerolipid] + 2 reduced ferredoxin [iron-sulfur] cluster + O(2) + 2 H(+) <=> a 1-acyl-2-((3E)-hexadec-3-enoyl)-[glycerolipid] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H(2)O

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.
