Open AccessStructural basis and synergism of ATP and Na+ activation in bacterial K+ uptake system KtrAB
The K+ uptake system KtrAB is essential for bacterial survival in low K+ environments. The activity of KtrAB is regulated by nucleotides and Na+. Previous studies proposed a putative gating mechanism of KtrB regu...
