abstract = {The crystal structures of three proteins of diverse function and low sequence similarity were analyzed to evaluate structural and evolutionary relationships. The proteins include a bacterial bleomycin resistance protein, a bacterial extradiol dioxygenase, and human glyoxalase I. Structural comparisons, as well as phylogenetic analyses, strongly indicate that the modern family of proteins represented by these structures arose through a rich evolutionary history that includes multiple gene duplication and fusion events. These events appear to be historically shared in some cases, but parallel and historically independent in others. A significant early event is proposed to be the establishment of metal-binding in an oligomeric ancestor prior to the first gene fusion. Variations in the spatial arrangements of homologous modules are observed that are consistent with the structural principles of three-dimensional domain swapping, but in the unusual context of the formation of larger monomers from smaller dimers or tetramers. The comparisons support a general mechanism for metalloprotein evolution that exploits the symmetry of a homooligomeric protein to originate a metal binding site and relies upon the relaxation of symmetry, as enabled by gene duplication, to establish and refine specific functions.},
