Figure 1. Crystal structure of Tth RbfA and its comparison with known atomic structures of RbfA from other species.

Figure 1

(A) Stereo representation of the Tth RbfA is shown in cartoon (PDB code: 2DYJ). (B) An enlarged view of the helix-kink-helix motif (cyan) with all residues in stick. Residues involved in notable interactions, Asp25 and Arg27 on the 310 helix (magenta) and the conserved Phe87, are also shown in stick. (C) Stereo representation of Tth RbfA in the surface potential prepared by using APBS tools built in PyMOL. (D) Superposition of structures of RbfA from T. Thermophilus (molecules A and B in the asymmetric unit are shown in dark and light blue colors, respectively), H. influenzae (green, 1JOS) and M. pneumoniae (orange, 1PA4). In all panels, N, C, and hkh mean N-terminus, C-terminus and helix-kink-helix motif, respectively.
