ID 1.14.19.42 DE palmitoyl-[glycerolipid] 7-desaturase. CA a 1-acyl-2-hexadecanoyl-glycerolipid + 2 H(+) + O2 + 2 reduced [2Fe-2S]- CA [ferredoxin] = a 1-acyl-2-[(7Z)-hexadecenoyl]-glycerolipid + 2 H2O + CA 2 oxidized [2Fe-2S]-[ferredoxin]. CC -!- The enzyme introduces a cis double bond at carbon 7 of a palmitoyl CC group attached to the sn-2 position of glycerolipids. CC -!- The enzyme from the plant Arabidopsis thaliana is specific for CC palmitate in monogalactosyldiacylglycerol. DR Q949X0, ADS3_ARATH ; //
