(This article belongs to the Special Issue Expanding and Reprogramming the Genetic Code)
The authors wish to make the following two corrections to this paper [1]:
1. In Figures 2 and 5, a false structure of the noncanonical amino acid Nε-Bicyclo[6.1.0]non-2-yn-9-ylmethoxycarbonyl-l-lysine 5 has been shown. The corrected Figure 2 should be replaced with the following figure (Figure 1), the cor-rected Figure 5 should be replaced with the following figure (Figure 2).
2. The authors wish to add the grant number “ERC-CoG EPICODE to D.S., Grant Nr. 723863” to the Acknowledgments section.
The authors would like to apologize for any inconvenience caused to the readers by these changes.
