Part:BBa_K5133007
Microcin M
Group: GEC-China (iGEM 2024, team number: #5133)
Brief introduction
This basic part is derived from plasmid pFB398[1], including a DNA sequence for coding Microcin M, an antimicrobial peptide produced by probiotic E. coli Nissle 1917. By assembling with T7 promoter (BBa_K5133000), RBS (BBa_K5133001), and T7 terminator (BBa_K5133003) derived from plasmid pJL1[2], this part is used for the construction of composite part BBa_K5133008 to demonstrate the in vitro production of antimicrobial peptides by CFPS.
Design and characterization
The plasmid design of this biological part is shown as Figure 1, assembled with iGEM standard backbone pSB1C3. To validate the correctness of DNA sequence, result of Sanger sequencing for BBa_K5133008 show the successful assembly among T7 promoter (BBa_K5133000), RBS (BBa_K5133001), Microcin M (this part), and T7 terminator (BBa_K5133003) in Figure 2.
Usages
This part is used for the construction of composite part BBa_K5133008 (Microcin M generator) to demonstrate the feasibility of in vitro antimicrobial peptide production by CFPS.
