The crystal structure of monomeric (PDB ID: [http://www.rcsb.org/pdb/explore/explore.do?structureId=3A43 3A43]) and <scene name='Heidi_Hu/Sandbox_2/Hypa_switch_dimer/4'>homodimeric</scene> (PDB ID: [http://www.rcsb.org/pdb/explore/explore.do?structureId=3A44 3A44]) HypA from [http://en.wikipedia.org/wiki/Thermococcus_kodakarensis ''Thermococcus kodakarensis''] has been solved<ref>PMID:19769985</ref>.  The HypA homodimer from [http://en.wikipedia.org/wiki/Thermococcus_kodakarensis ''T. kodakarensis''] shows a switch dimer, where one beta strand of each alpha/beta lobe comes from the opposite subunit.  Additionally, each Zn(II) site is coordinated by CXXC motifs from a different subunit. These observations were consistent with the [http://en.wikipedia.org/wiki/Helicobacter_pylori ''H. pylori''] homodimeric HypA NMR data<ref name="bob"/>.
