Fig. 2: The dimeric assembly of ReAV.
From: Crystal structures of the elusive Rhizobium etli l-asparaginase reveal a peculiar active site
a In the C2 dimer, the active sites are located in the center of each subunit and contain Zn2+ cations. b Molecular surface of the dimer, showing a tunnel of ~20 Å diameter. c Residues forming the dimer stabilization domain and helices H7 are marked as spheres. d A perpendicular view showing that the area involved in dimer stabilization extends across the dimer to include many hydrogen bonds formed between main-chain and side-chain atoms.
