Fig. 2

a Derived cryo-EM map and model of the asymmetric subunit; the fitting is magnified in the inset. b Representative resolution features of the atomic model fitted in the 3.21 Å cryo-EM map. In green, a close-up of a β-sheet is shown with the separation of the single strands clearly visible in the density of the map; in blue, an α-helix is shown with helical pitch discernible; side chain density is often distinguishable. c Representative cation-π interactions are shown between arginine and tyrosine, tryptophan or phenylalanine within chain A (green), chain B (blue), or between chain A and an adjacent chain B (slate). The 3.21 Å cryo-EM density map is shown as transparent volume.
