ID 1.14.19.6 DE Delta(12)-fatty-acid desaturase. AN Delta(12) desaturase. AN Delta(12) fatty acid desaturase. AN Delta(12)(omega-6)-desaturase. AN Delta(12)-desaturase. AN Oleoyl-CoA Delta(12) desaturase. CA Acyl-CoA + reduced acceptor + O(2) = Delta(12)-acyl-CoA + acceptor + CA 2 H(2)O. CC -!- In the yeast Lipomyces starkeyi and in the American cockroach CC Periplaneta americana, this microsomal enzyme converts oleoyl-CoA CC into linoleoyl-CoA. CC -!- In the moths Cadra cautella and Spodoptera, the enzyme converts (Z)- CC 9-tetradecenoic acid into (9Z,12E)-tetradeca-9,12-dienoic acid, which CC is reduced and acetylated to form the acetate ester pheromone. CC -!- Formerly EC 1.14.19.n3. PR PROSITE; PDOC00399; DR Q9Y8H5, FAD12_MORAP; P59668, FAD12_MORIS; //
