Figure 1A is a composite image constructed from separate experimental runs. This was not properly described in the figure caption. A new composite Figure 1A is included, showing clearly that the lanes come from different experiments. The primary KCs/YBL panel was erroneously inserted in duplicate in Figure 2. A new Figure 2 is also included, where the duplicate panel has been replaced with genuine HaCat/YBL results. These errors neither affect the results nor the conclusion of the article. The authors apologize to the readers and publisher for any inconvenience, which might have been caused.
