Author Correction: Convergent evolution of a modified, acetate-driven TCA cycle in bacteria

In this Brief Communication, the authors omitted references to several previous studies that have demonstrated that the TCA variant shown has also been found in several other bacterial species, specifically among some anaerobic Deltaproteobacteria. The Brief Communication focused on showing that this variant is more widespread than previously known, particularly in animal-associated bacteria. Using genetic approaches, Kwong et al. demonstrated this alternative cycle in additional, distantly related organisms. Thus, the previous work does not affect the results of the advance provided. However, the previous studies are relevant to this topic and should have been cited, and Kwong et al. apologize for this for the omission. Citations to several of the studies should have been included as refs 9-13 in the text as shown.
