ID   1.14.19.43
DE   palmitoyl-[glycerolipid] 3-(E)-desaturase.
CA   a 1-acyl-2-hexadecanoyl-glycerolipid + 2 reduced [2Fe-2S]-[ferredoxin] +
CA   O2 + 2 H(+) = a 1-acyl-2-[(3E)-hexadec-3-enoyl]-glycerolipid + 2 oxidized
CA   [2Fe-2S]-[ferredoxin] + 2 H2O.
CC   -!- The enzyme introduces an unusual trans double bond at carbon 3 of a
CC       palmitoyl group attached to the sn-2 position of glycerolipids.
CC   -!- The enzyme from the plant Arabidopsis thaliana is specific for
CC       palmitate in phosphatidylglycerol.
CC   -!- The enzyme from tobacco can also accept oleate and alpha-linolenate
CC       if present at the sn-2 position of phosphatidylglycerol.
