== Publication Abstract from PubMed ==
RNase D (RND) is one of seven exoribonucleases identified in Escherichia coli. RNase D has homologs in many eubacteria and eukaryotes, and has been shown to contribute to the 3' maturation of several stable RNAs. Here, we report the 1.6 A resolution crystal structure of E. coli RNase D. The conserved DEDD residues of RNase D fold into an arrangement very similar to the Klenow fragment exonuclease domain. Besides the catalytic domain, RNase D also contains two structurally similar alpha-helical domains with no discernible sequence homology between them. These closely resemble the HRDC domain previously seen in RecQ-family helicases and several other proteins acting on nucleic acids. More interestingly, the DEDD catalytic domain and the two helical domains come together to form a ring-shaped structure. The ring-shaped architecture of E. coli RNase D and the HRDC domains likely play a major role in determining the substrate specificity of this exoribonuclease.
