Figure 3. Monomer-monomer interfaces in the AnsA tetramer.

Figure 3

Panels (a) and (c) show the intimate dimer (A/C) interface in the apo structure and the asparagine-bound structure, respectively. Panels (b) and (d) show stereoviews of the loose dimer (A/B) interface in the apo structure and the asparagine-bound structure, respectively. Monomer A is yellow, B is green and C is in cyan, and the two allosteric asparagine molecules in (c) have red carbon atoms. Details are provided in the text.
