Table 1. Crystallographic data processing and refinement statistics.

https://doi.org/10.1371/journal.pone.0134070.t001

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 [26] and scaled with Aimless [27] from the CCP4 suite of programs [28] (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/R_free values of 0.141/0.183) (Fig 3A) and AMP to 1.80 Å resolution (R/R_freevalues 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%.
