Part:BBa_K5133002

sfGFP (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 an DNA sequence for coding sfGFP (superfolder green fluorescent protein). The plasmid pJL1 is commonly used for the in vitro sfGFP expression of cell-free protein synthesis (CFPS)^[2]. Hence, this part is used for the construction of composite part BBa_K5133004 to demonstrate the feasibility of 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. To validate the correctness of DNA sequence, result of Sanger sequencing for BBa_K5133004 show the successful assembly among T7 promoter (BBa_K5133000), RBS (BBa_K5133001), sfGFP (this part), and T7 terminator (BBa_K5133003). (Figure 2).

Usages

This part is used for the construction of composite part BBa_K5133004 (sfGFP generator) to demonstrate the feasibility of CFPS in our project.
