In the version of this News and Views originally published, references 7 and 8 were swapped in the reference list. Reference 7 should be “Metrick, C. M. et al. Nat. Chem. Biol. https://doi.org/10.1038/s41589-019-0458-4 (2020)” and reference 8 should be “Bowling, F. Z. et al. Nat. Chem. Biol. https://doi.org/10.1038/s41589-020-0499-8 (2020). The error has been corrected in the HTML and PDF versions of the paper.
