In the initial published version of this article, we omitted the reference to an earlier paper [1] that showed that phosphorylation on Ser1157 was reduced by 50% in snf1 yeast cells and that the S1157A mutant cells could not grow on media-lacking inositol. The addition of this reference does not affect the results, figures, and conclusion of the paper.
