Protein coding sequence
The synthetic Cry1B.868 protein comprises domain 1 (D1) and domain 2 from Cry1Be2 (M1 to I503), domain 3 from Cry1Ca1 (N468 to N633), and the C-terminal protoxin moiety (domains 4 to 7) from Cry1Ab3 (E626 to E1155). The protein binds different receptors compared to other commonly available Bt proteins, such as Cry1F, Cry1A.105, Cry2Ab and Vip3A, but continues to demonstrate a pore-forming mode of action. Thus, the protein causes mortality and developmental delay in susceptible Lepidoptera insects, such as fall armyworm. In assays using Cry1F-resistant fall armyworm colonies, the protein overcame the insect's Bt-resistance.EN
