Figure 3: Dimerization of HypBA1. (A) Dimeric HypBA1 structure with one bound L-Araf molecule and a Zn2+ ion in each monomer (Figure 1). Because there is only one molecule in an asymmetric unit, the dimer is constructed by generating a symmetry-related partner. For clarity, the contact domains are presented in different colors (green versus wheat and cyan versus grey). (B) Front view of the HypBA1 dimer. (C) Close-up view of the interaction network of salt bridges at the dimer interface.
