Structural comparison of the three AB pairs in state1. a The EM map in state1 with focus on the V1EGd (A3B3DF(EGCT)2d) subdomain. The density of the membrane embedded region was subtracted by focused refinement using the mask of V1EGd. The map is shown in semi-transparent gray. Scale bar, =30 Å. b Side views of the three AB pairs, “closed”, “semi-closed”, and “open” corresponding to those of the cross-section shown in Fig. 1c. Scale bar, =20 Å. c Magnified views of the nucleotide-binding site at each AB pair. ADP is depicted in ball and sticks format. Experimental maps are shown in semi-transparent gray. Scale bar, =5 Å
