Design Notes

This construct was designed to not contain any other amber stop codon but at position 31 (Lys31X) (Amberless E. coli must be used to see the effects of photocageing spyCatcher). We decided to fuse SpyCatcher 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 SpyCatcher to facilitate mobility of SpyCatcher on the cell surface and a HisTag for protein purification.

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. SpyCatcher was obtained from: BBa_K1159200. The DNA sequence was synthesised by Integrated DNA Technologies (IDT)
