Figure 1. . Comparison of deduced amino-acid-sequences for insect desaturases from Argyrotaenia velutinana (Ave), Choristoneura rosaceana (Cro), Epiphyas postvittana (Epo), Heliothis zea (Hze), Ostrinia nubilalis (Onu), Planotortrix octo (Poc), and Tricoplusia ni (Tni). The Z9 desaturases are classified as Z9(16) or Z9(18) to define whether they produce more Z9-16:Acid or more Z9-18:Acid. The three histidine domains are boxed in red.
