Correction to: Nature Reviews Chemistry https://doi.org/10.1038/s41570-023-00471-4. Published online 18 April 2023.

In the version of this article initially published, above the right-hand side reaction arrow of Figure 4a, “UGT1A1” was shown as “UGT-1A.” In Figure 6a and 6c, “RN+H3” was mistakenly presented as “H3N+” and “N+H3,” respectively. The errors have been corrected in the HTML and PDF versions of the article.
