Design Notes

We created this specific aaRS by ordering a gene synthesis at Integrated DNA Technologies (IDT) with a codon optimized sequence of an aaRS able to incorporate 2-NPA, based on an evolution experiment of Peters et al. This gene synthesis was integrated into the ONBY-Part K1416000, replacing the ONBY-RS. This approach is applicable, as the 2-NPA-RS and the ONBY-RS are mutated versions of the M. jannaschii TyrRS, such that both recognize the same tRNA and only the sequence of the aaRS itself has to be changed to get a new synthetase binding other amino acids to the tRNA. The gene synthesis we ordered had 30 base pairs overlap to a linearized vector of the ONBY-part K1416000, where only the gene sequence of the ONBY-RS was removed. The fragment of the NPA-RS was integrated by Gibson assembly (Figure 1.
