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.

Gibson Assembly Design

Insert: we amplified the streptavidin coding sequence received in a plasmid from Mark Howarth laboratory at Oxford university Dept. of Biochemistry.
Backbone: Starting from the biobrick BBa_K523013 (INP fused with YFP), we amplified the whole sequence except the EYFP and added gibson overhang complementary to streptavidin ends.
