Publication Abstract from PubMed The crystal structure for cce_0566 (171 aa, 19.4kDa), a DUF269 annotated protein from the diazotrophic cyanobacterium Cyanothece sp. ATCC 51142, was determined to 1.60A resolution. Cce_0566 is a homodimer with each molecule composed of eight alpha-helices folded on one side of a three strand anti-parallel beta-sheet. Hydrophobic interactions between the side chains of largely conserved residues on the surface of each beta-sheet hold the dimer together. The fold observed for cce_0566 may be unique to proteins in the DUF269 family, hence, the protein may also have a function unique to nitrogen fixation. A solvent accessible cleft containing conserved charged residues near the dimer interface could represent the active site or ligand-binding surface for the protein's biological function.
