Structural insights into the dual activity of RNase J. la Sierra-Gallay, L.Zig, A.Jamalli, H.Putzer.
The maturation and stability of RNA transcripts is controlled by a combination of endo- and exoRNases. RNase J is unique, as it combines an RNase E-like endoribonucleolytic and a 5'-to-3' exoribonucleolytic activity in a single polypeptide. The structural basis for this dual activity is unknown. Here we report the crystal structures of Thermus thermophilus RNase J and its complex with uridine 5'-monophosphate. A binding pocket coordinating the phosphate and base moieties of the nucleotide in the vicinity of the catalytic center provide a rationale for the 5'-monophosphate-dependent 5'-to-3' exoribonucleolytic activity. We show that this dependence is strict; an initial 5'-PPP transcript cannot be degraded exonucleolytically from the 5'-end. Our results suggest that RNase J might switch promptly from endo- to exonucleolytic mode on the same RNA, a property that has important implications for RNA metabolism in numerous prokaryotic organisms and plant organelles containing RNase J orthologs.
  Selected figure(s)  
Figure 1.
(a) Structure of the RNase J monomer. The -strands and -helices are labeled, and the two zinc ions in the active site are represented as yellow spheres. The sulfate ion is shown as a stick model. The N- and C-terminal ends of the protein are indicated by the letters N and C, respectively. See Supplementary Figures 3 and 4 for the RNase J secondary structure and topology. The loops and -strands shown in red are not present in RNase Z and CPSF-73. (b) Structure of the crystallographic dimer. One monomer is drawn in the same color code as in a, the second monomer is in gray. (c) The zinc binding site for RNase J in the absence of a ligand, with a nearby complexed sulfate ion. The zinc ions are shown as yellow spheres. Ligand-mediated and hydrogen-bond interactions are indicated by dotted orange lines. (d) The catalytic center of RNase J complexed with a UMP residue. The UMP phosphate moiety is located in the site occupied by a sulfate ion in the free enzyme and is held in place by interacting with the same residues that coordinated the sulfate.
Figure 2.
(a) Comparison of the electrostatic surfaces of RNase J and RNase E. Both structures are presented with the active site facing upwards. The UMP residue and the Mg^2+ ion in the catalytic sites of RNases J and E, respectively, are indicated. (b) Topology of the C-terminal domains of RNase J and RNase E. The two domains share the same architecture, a three-stranded -sheet facing two -helices.

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.
