T4F ATPase motor proteins. (A) Structure of hexameric PilT from Aquifex aeolicus with each monomer in a different color (PDB ID: 2GSZ) (B) Monomer of PilT from panel A showing the two domains. (C) Aligned PilB (P. stutzeri), PilT (P. stutzeri), ComGA (S. pneumoniae), and TadA (M. luteus) sequences. (D) Phylogenetic tree of putative motor proteins showing PilB (from T. thermophilus, H. influenza, M. catarrhalis, N. meningitidis, P. stutzeri, and A. nosocomialis), ComGA (from B. subtilis, S. aureus, and S. pneumoniae), PilT/U (from A. nosocomialis, P. stutzeri, T. thermophiles, and M. catarrhalis), and TadA (M. luteus) branches.
