T7 Promoter+RBS+Hv1a+linker+6X His-Tag

Introduction:

      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, an automatic detector, a 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. A 6xHistag is added for further protein purification.

Mechanism of Hv1a

      According to the reference, Omega-hexatoxin-Hv1a has a structure called ICK(inhibitor cysteine knot).^[1] 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.
