T7 promoter (from plasmid pJL1)
Group: GEC-China (iGEM 2024, team number: #5133)
Brief introduction
This basic part is derived from plasmid pJL1 (Addgene: #69496)[1], including a conserved DNA sequence of T7 promoter as 5'-taatacgactcactatagggaga-3'[2]. The plasmid pJL1 is commonly used for the in vitro sfGFP expression of cell-free protein synthesis (CFPS)[3]. Hence, this part is used for the construction of three composite parts: BBa_K5133004 (sfGFP generator), BBa_K5133006 (Microcin H47 generator), and BBa_K5133008 (Microcin M generator), for CFPS in our project.
Design and characterization
The plasmid design of this biological part is shown as Figure 1, assembled with iGEM standard backbone pSB1C3. Result of Sanger sequencing shows the correct construction of this part (Figure 2).
Usages
This part is used for the construction of three composite parts: BBa_K5133004 (sfGFP generator), BBa_K5133006 (Microcin H47 generator), and BBa_K5133008 (Microcin M generator), for CFPS in our project.
