In the above article, the sentence “The ubiquitin-like modifier-activating enzyme ATG7 ubiquitylates autophagy protein 5 (ATG5) so that it can form a functional complex with ubiquitin-like protein ATG12” should have appeared as “The ubiquitin-like modifier-activating enzyme ATG7 conjugates autophagy protein 5 (ATG5) with ubiquitin-like protein ATG12 so that it can form a functional complex”. In Figure 1 of the same article, ATG7 was incorrectly shown to be ubiquitylating ATG5, instead of conjugating ATG5 to ATG12. These errors have been corrected in the online version of the article.
