Correction to: Nature Communications https://doi.org/10.1038/s41467-019-09392-7, published online 04 April 2019.

In the first corrected version of this Article, the third sentence of the Discussion incorrectly read ‘The linear relationship of ln(kET) vs. Rab gives β = 1.25’. The corrected version states ‘1.25 Å−1’ instead of ‘1.25’. This has now been corrected in both the PDF and HTML versions of the Article.
