DE   sn-1 stearoyl-lipid 9-desaturase.
CA   a 1-octadecanoyl 2-acyl-glycerolipid + 2 reduced [2Fe-2S]-[ferredoxin] +
CA   O2 + 2 H(+) = a 1-[(9Z)-octadecenoyl]-2-acyl-glycerolipid + 2 oxidized
CA   [2Fe-2S]-[ferredoxin] + 2 H2O.
CC   -!- The enzyme, characterized from cyanobacteria, introduces a cis double
CC       bond at carbon 9 of stearoyl groups (18:0) attached to the sn-1
CC       position of glycerolipids.
CC   -!- The enzyme is non-specific with respect to the polar head group of
CC       the glycerolipid.
