a, Alphafold3-predicted structures of the motor protein ArlI and ArlJ of the bacterial organism L. aerophila, the euryarchaeon M. jannaschii and S. acidocaldarius (PDB: 4ii7 for ArlI). A comparison of all three structures reveals remarkable structural similarity and similar domains in the N-terminal domain (NTD) and C-terminal domain (CTD). b, Conservation of residues in ArlI and ArlJ of bacterial archaella machineries was calculated using ConSurf. The scale bar indicates calculated conservation scores per residue. Predicted local distance difference test (pLDDT) plots of predicted structures are found in Supplementary Fig. 2.
