Lactose Permease H(+)-Lactose Symporter: Mechanical Switch or Brownian Ratchet?

Lactose permease structure is deemed consistent with a mechanical switch device for H(+)-coupled symport. Because the crystallography-assigned docking position of thiodigalactoside (TDG) does not make close contact with several amino acids essential for symport; the switch model requires allosteric...
