Superposition of the C- and N-terminal domains of Δ18PA1624 with structurally related proteins. Δ18PA1624 is color-coded according to its secondary-structure elements. (a) The N-terminal domain superposes on the full-length lipoprotein DcrB from S. enterica, colored light blue (PDB entry 6ea8), with a Cα r.m.s.d. of 3.2 Å over 101 amino acids. (b) The smaller C-terminal domain structurally aligned with the blue-colored domain of Tp0624 from Treponema pallidum with a Cα r.m.s.d. of 2.8 Å over 78 residues (PDB entry 5jir). (c) Superposition of the C-terminal domain of PA1624 with full-length Tp0624 from T. pallidum. |
