Figure 7. Quaternary structure of the Mtb Tpx. (a) Dimer interface with residues making hydrogen bond contacts shown in ball-and-stick representation. (b) Overall shape and interface of dimer−dimer interactions. A rectangle indicates a close view of dimer−dimer interfaces. Dimers are shown in yellow (molecules A and B) and red (molecules C and D). Residues making close contacts interactions are shown with ball-and-stick representations. Hydrogen bonds are indicated by dotted lines.
