MTH1859 from Methanobacterium thermoautotrophicum is a 77 residue protein representing a conserved family of functionally uncharacterized proteins. We solved the crystal structure of MTH1859 by single wavelength anomalous diffraction phasing using selenomethionine labeled protein. MTH1859 adopts a mainly anti-parallel all-beta-fold. The beta-sheet is heavily bent to form a U-structure that is closed through a loop. The monomer structure possesses similarities to the photoreaction center (PRC) domain fold, but the protein employs a unique oligomerization scheme. Two monomers of MTH1859 occupy the asymmetric unit and dimerize in a head-to-head fashion. Crystal packing interactions identify a second protein-protein interaction interface at the MTH1859 tails which can simultaneously bind two partner molecules. These interactions lead to the formation of a honeycomb structure and suggest that the family of MTH1859-like proteins might function as adapters for protein complex assembly.
