By ligating the IPTG induced promoter T7 (BBa_ I712074), strong ribosome binding site (BBa_B0034), hv1a, linker, and the 6xHistag (BBa_ K1223006), we can express Hv1a, the toxin by IPTG induction
This year we create a revolutionary system that integrates biological pesticides, automatic detector, sprinkler, and IoT. We made a database that contains most of the spider toxins and selected the target toxins by programming. Omega-hexatoxin-Hv1a is coded for the venom of a spider, Hadronyche versuta.
It is under the control of the strong T7 promoter. Snowdrop-lectin acts as a carrier that could transport the toxin to insect’s nervous system, hemolymph and can improve the oral activity. A 6xHistag is added for further protein purification.
Mechanism of Hv1a:
According to reference, snowdrop-lectin is resistant to high temperature and would not be degraded by digestive juice. The species-specificity is based on the toxin, and the snowdrop lectin is the role of the carrier.
According to reference, Omega-hexatoxin-Hv1a has a structure called ICK(inhibitor cysteine knot).[1](之前PPT裡有) This kind of structure contains three disulfide bonds and beta-sheet. With this structure, Hv1a can resist the high temperature, acid-base solution and the digest juice of insect gut. Hv1a can bind on insect voltage-gated Calcium channels (CaV1) in the central nervous system, making it paralyze and die eventually.
