Design Notes

3. What we have done? (SCAU-China 2023)

In our design, the coding gene fragment for the active Cry3A-like toxin will be transformed into E. coli by the pET-30a vector, to confer the ability to produce Cry3A-like toxin.

To enable its secretion, a signal peptide sequence, OmpA, was added to the N-terminal of the Cry3A-like toxin. OmpA is a well-studied signal peptide in E.coli for the secretion of foreign proteins. (Figure 1 )

Furthermore, we fused a 6×His tag to the C-terminus of Cry3A-like toxin to facilitate subsequent protein purification and Western blot-specific characterization experiments.(Figure 2 )

We obtained the sequence of the active Cry protoxin of UTD-001 from the original literature. After codon optimization, we entrusted GUANGZHOU IGE BIOTECHNOLOGY LTD to synthesize the gene fragment OmpA-active Cry protoxin of UTD-001.
