Design Notes

We decided to fuse SpyTag to the N-terminal of a truncated version of Intimin as this has been previously proven to function effectively for cell surface display of up to 30kDa passenger proteins (Wentzel et al., 2001). We also included a linker between Intimin and SpyTag to facilitate mobility of SpyTag on the cell surface.

Source

Intimin protein sequence obtained from UniProtKB: [http://www.uniprot.org/uniprot/P43261#sequences P43261], reverse translated and codon optimised for E. coli. Intimin for the cell surface display of our tag was truncated according to Wentzel et al., 2001. SpyTag was obtained from: BBa_K1159201. The DNA sequence was synthesised by Integrated DNA Technologies (IDT)
