show Brenda entryEC number
1.14.19.28
Accepted name
sn-1 stearoyl-lipid 9-desaturase
Reaction
a 1-stearoyl-2-acyl-[glycerolipid] + 2 reduced ferredoxin [iron-sulfur] cluster + O2 + 2 H+ = a 1-oleoyl-2-acyl-[glycerolipid] + 2 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O
Other name(s)
desC (gene name)
Systematic name
1-stearoyl-2-acyl-[glycerolipid],ferredoxin:oxygen oxidoreductase (9,10 cis-dehydrogenating)
Comment
The enzyme, characterized from cyanobacteria, introduces a cis double bond at carbon 9 of stearoyl groups (18:0) attached to the sn-1 position of glycerolipids. The enzyme is nonspecific with respect to the polar head group of the glycerolipid.
