In the version of the article originally published, it was not clarified that the raw data used to obtain one of the refined structural models for the 2F state (PDB 8EZ5) were the same as those used to obtain the previously reported structural models PDB 6W1V and PDB 7RF8. This clarification has now been added as a footnote to Extended Data Table 1.
