Design Notes

This composite part includes the IPTG-inducible T7 promoter (BBa_J64997), RBS BBa_B0034, Lbu-Cas13a with an N-terminal 6xHistidine Tag and C-Terminal Anionic Tag coding region (BBa_K3738020), and double terminator BBa_B0015.The part is codon-optimized for use in E. coli It is improved from the Lethbridge High School iGEM 2019's Parts BBa_K3001003, BBa_K3001000 and BBa_K3001002 by introducing the anionic MS2 phage-like-particle uptake anionic tag as well as the transcriptional and translational regulators for optimal overexpression and 6XHistidine tag required for nickel affinity chromatography purification.
