Abstract excerpt
The Sm family of proteins is closely associated with RNA metabolism throughout all life. These proteins form homomorphic and heteromorphic rings consisting of six or seven subunits with a characteristic central pore, the presence of which is critical for binding U-rich regions of single-stranded RNA. Eubacteria and Archaea typically carry one or two forms of Sm proteins and assemble one homomorphic ring per Sm...
