Cryo-EM map of the PBS core from the front (a, c), side (b, e, f), and bottom (d) views. c It shows the superposition of the cryo-EM map and the refined PBS core model. e Here it shows the structure inside the rectangle in a, enlarged and rotated 90˚. f This shows e rotated 180˚. g Schematic model of the pentacylindrical APC core (including A (A’), B, and C (C’) cylinders) and PC rods (Rb, Rb’, Rt, and Rt’). ApcE (LCM) containing α, Reps 1–4 and Arms 1–3 is shown in red. PC rods that did not build the model are shown in translucent. The PC rod models were drawn referencing the cryo-EM map in this study and the PBS structure from Nostoc 71207. h Schematic model of the PC rod. CpcC (LR), CpcD (LRT), and CpcG (LRC) interact within the two PC hexamers. The identification of ApcD is tentative. ApcD is shown in parentheses (ApcD).
