Two examples of improper Mg2+ assignments in the 6SJ6 cryo-EM structure at 3.23 Å resolution (Khusainov et al. 2020). (A) The coordination distance to this ion excludes the presence of Mg2+ and rather suggests the presence of K+. (B) Note the large B-factor discrepancy that further suggests the presence of K+.
