title: Halobacterial S9 operon contains two genes encoding proteins homologous to subunits shared by eukaryotic RNA polymerases I, II, and III.
abstract: One key component of the eukaryotic transcriptional apparatus is the multisubunit enzyme RNA polymerase II. We have discovered that two of the subunits shared by the three nuclear RNA polymerases in the yeast Saccharomyces cerevisiae, RPB6 and RPB10, have counterparts among the Archaea.
