Crystal structure of Escherichia coli RNase D, an exoribonuclease involved in structured RNA processing.
Y.Zuo, Y.Wang, A.Malhotra.
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.

Figure 1. Multiple Alignment of RNase D-Related Sequences
Sequences are from the NCBI nonredundant protein sequence database. Sequence included here are: RND_ECOLI, E. coli RNase D (accession no. G133152); RND_MYCTU, M. tuberculosis Rv2681 protein, a putative RNase D (G15609818); RND_AGRTU, putative A. tumefaciens RNase D (G13195121); RRP6_YEAST, S. cerevisiae RRP6 protein, an exosome component (G14195186); PMC2_HUMAN, the human RRP6 equivalent (G8928564); RND_RICPR, putative R. prowazekii RNase D (G7467941); RND_SYNY3, putative Synechocystis RNase D (G1001530); and RND2_AGRTU, another A. tumefaciens RNase D-related protein (G17937803). These sequences are chosen because they are representative: RRP6_YEAST and PMC2_HUMAN are eukaryotic RNase D homologs; RND_MYCTU and RND_AGRTU are two distant bacterial homologs of E. coli RNase D; the other three sequences are distantly related to E. coli RNase D, but lacking one (RND_RICPR) or both (RND_SYNY3 and RND2_AGRTU) C-terminal domains. This sequence alignment was initially generated by ClustalX and manually adjusted based on secondary structure predictions due to very weak sequence conservation, especially at the C-terminal domain. Many other related sequences (not shown) have been used to help produce this sequence alignment. The conserved DEDDy residues are marked with red triangles, and are distributed among three exo motifs (Zuo and Deutscher, 2001). Residues conserved among most RNase D homologs are boxed and colored. Highly conserved residues are highlighted in red. The numbering on the top is according to E. coli RNase D sequence.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
