Extended Data Fig. 11: PBS rod conformation.

a, Side view of AcpAB disc showing the groove network that organizes CpcG1 linker attachment to the PBS core. Selected residues are labeled. b, Salt bridge formed between two neighboring rods when the mobile rod adopts the ‘down’ conformation. EM density is transparent, dark grey and shows the conformation of R150 when the mobile rod is ‘up’. A bilin molecule in very close proximity of R150 of CpcB is also shown.
