Design Notes

This part has been codon optimized for use in E. coli. The anionic tag is present to facilitate uptake into our delivery particle MS2 whereas the Histidine tag was added for the purpose of Nickel-Affinity chromatography in obtaining the purified protein.

This composite part includes the IPTG-inducible T7 promoter (BBa_J64997), RBS BBa_B0034, Lbu-Cas13a with an N-terminal Anionic Tag and C-Terminal 6xHistidine Tag coding region(BBa_K3738021), and double terminator BBa_B0015.



Source

The Cas13a protein comes from the Gram-negative bacteria Leptotrichia buccalis (Lbu).
