Structure of the Methanothermobacter thermautotrophicus exosome RNase PH ring

The core of the exosome, a versatile multisubunit RNA‐processing enzyme found in archaea and eukaryotes, includes a ring of six RNase PH subunits. This basic architecture is homologous to those of the bacterial and archaeal RNase PHs and the bacterial polynucleotide phosphorylase (PNPase). While all...
