Design Notes

A stop codon (TAA) and the nucleotide G are added immediately upstream of BBa_K731721 (T7 terminator). This extra stop codon (assuming the fusion protein sequence has its own) ensures that translation is halted and prevents any translational read-through. The extra nucleotide G is added for a more subtle purpose: when placed just before the T7 terminator sequence (5'-CTAGC...TTTTG-3'), it forms the NheI restriction site (G\CTAGC). This allows any fusion protein to be inserted into our expression backbone using the HindIII and NheI sites.

Source

This short sequence was added using PCR, with primers having 5'-overhangs corresponding to these nucleotides.
