The original version of this Article contained errors in Figures 1 and 4. In Fig. 1b, the Mtb-SecBTA sequence was displayed incorrectly. In the inset panel within Fig. 4c, the y-axis of the graph incorrectly read (Q.Rg)2 × I(Q)//(0), and should have read (Q.Rg)2 × I(Q)/I(0). These errors have been corrected in both the PDF and HTML versions of the Article.
