In the originally published version of this article, there was a typo in Figure 4D. The amino acid substitutions were referred to as Q226/G228 instead of L226/S228. This has since been corrected online. The corrected and original versions of Figure 4D are shown here. The authors apologize for any confusion this error may have caused.
