Correction: The PCNA Interaction Protein Box Sequence in Rad54 Is an Integral Part of Its ATPase Domain and Is Required for Efficient DNA Repair and Recombination

A reference is omitted from the fourth sentence of the second paragraph under the subheading ‘‘Mutational analysis of the PIPbox domain’’ in the Results and Discussion section. The sentence should read: A complementary study performed independently in the Heyer laboratory came to the same set of conclusions (Zhang et al., 2013). The reference is: Zhang X-P, Janke R, Kingsley J, Luo J, Fasching C, et al. (2013) A Conserved Sequence Extending Motif III of the Motor Domain in the Snf2-Family DNA Translocase Rad54 Is Critical for ATPase Activity. PLoS ONE 8(12): e82184. doi:10.1371/journal.pone.0082184
