In the version of this article initially published, due to a figure preparation error, the image shown in the upper-middle panel of Extended Data Fig. 2d for the Cflar KI dot plot was an inadvertent duplicate of the adjacent dot plot (wild-type). Due to the age of the article, the figure cannot be updated directly; the revised Extended Data Fig. 2, panel d, is available as Supplementary Information alongside this amendment.
In the version of the article initially published, in Fig. 2a, the y axis of the middle panel was shifted upwards and has now been moved down so that 0 is level with the x axis. In Fig. 3a, the RGB pixels dashed red line has been shortened for clarity. In Extended Data Fig. 2, the y-axis label was W (100 to 200 nm) but should have been W (100 to 220 nm).
