Design Notes

To assemble this part, we orderd a plasmid containing the streptavidin dead. Three point mutations have been made, N23A,S27D,S45A, in order to decrease the biotin-streptavidin Kd. This streptavidin is monovalent. We amplified only the coding sequence of streptavidin of the plasmid by PCR. Also, we did a PCR with overlapping ends corresponding to streptavidin on the Biobrick BBa_K523013 (INP fused with YFP). This PCR was keeping all the plasmid including RBS and Lac promoter but excluding YFP. The linearized plasmid and the insert were then assembled by Gibson assembly.
