H+ transfer from the retinal-Schiff-base (RSBH+) at the gating-on of ion transport. (A) In the case of BR, the primary H+ acceptor is D85. Modified from [39]. (B) In the case of hWR, E162 (BR D85 counterpart) and D292 (BR D212 counterpart), both of which are assumed to form a hydrogen-bond network with the indole-N group of W163, are candidates of the primary H+ acceptors. Modified from [25].
