Figure 1. Crystal Structure of Tth RbfA and Its Comparison
with Known Atomic Structures of RbfA from Other Species
(A)
Stereo representation of the Tth RbfA is shown in cartoon (PDB
ID, 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 3[10] 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.
