Exosomes emerge as central 3'-->5' RNA processing and degradation machineries in eukaryotes and archaea. We determined crystal structures of two 230 kDa nine subunit archaeal exosome isoforms. Both exosome isoforms contain a hexameric ring of RNase phosphorolytic (PH) domain subunits with a central chamber ...
