There is an error in the last sentence of the “TcdA crystallization, structure determination and refinement” subsection of the Materials and Methods. The correct sentence is: A data set for the AMP complex was collected to 1.80-Å resolution at the PROXIMA 2A beamline (Synchrotron SOLEIL, Paris, France). All the data sets were integrated with XDS  and scaled with Aimless  from the CCP4 suite of programs  (Table 1).
There are errors in the fifth and sixth sentences of the “Crystal structure of TcdA” subsection of the Results and Discussion. The correct sentences are: To shed light onto the structural basis for the tRNA binding and ct6A synthetic properties of TcdA-ATP, we determined the crystal structure of E. coli TcdA (Table 1 and Fig 2) loaded with ATP to 1.77 Å resolution (R/Rfree values of 0.141/0.183) (Fig 3A) and AMP to 1.80 Å resolution (R/Rfreevalues of 0.139/0.176) (Fig 3B). The asymmetric unit contained four TcdA chains arranged in two independent dimers, with a solvent content of 39%.
