Correction to: Nature https://doi.org/10.1038/s41586-018-0701-2, published online 07 November 2018.

In this Letter, owing to an error in the production process, author Martin Aichinger was inadvertently associated with affiliation 14 (Karolinska Institute, Department of Medicine Solna, Center for Molecular Medicine, Karolinska University Hospital Solna, Stockholm, Sweden) instead of affiliation 13 (Research Institute of Molecular Pathology, Vienna Biocenter, Campus-Vienna-Biocenter 1, Vienna, Austria). In addition, the chemical structure of QM385 in Fig. 3a was incorrect. Figure 1 of this Amendment shows the incorrect and corrected structures, for transparency. These errors have been corrected online.
