  ABSTRACT  
 
The C-terminal domain of the UvrC protein (UvrC CTD) is essential for 5' incision in the prokaryotic nucleotide excision repair process. We have determined the three-dimensional structure of the UvrC CTD using heteronuclear NMR techniques. The structure shows two helix-hairpin-helix (HhH) motifs connected by a small connector helix. The UvrC CTD is shown to mediate structure-specific DNA binding. The domain binds to a single-stranded-double-stranded junction DNA, with a strong specificity towards looped duplex DNA that contains at least six unpaired bases per loop ("bubble DNA"). Using chemical shift perturbation experiments, the DNA-binding surface is mapped to the first hairpin region encompassing the conserved glycine-valine-glycine residues followed by lysine-arginine-arginine, a positively charged surface patch and the second hairpin region consisting of glycine-isoleucine-serine. A model for the protein-DNA complex is proposed that accounts for this specificity.

Figure 3.
Figure 3 The NMR solution structure of the UvrC CTD. (A) Backbone stereo view (residues 28−78) of the NMR ensemble (22 structures); the hairpins are coloured in blue. (B) Ribbon view of a representative UvrC CTD structure (closest to average) for residues 23−78. h1 and h2 are the hairpins of HhH motifs. The structures were displayed using the molecular graphics program MOLMOL (Koradi et al., 1996).
Figure 7.
Figure 7 Model representing the interaction of the UvrC CTD with the ds−ss junction. Glycines are coloured red, lysine in blue and threonine in green. This model was obtained by superimposing the two hairpins of UvrC CTD on to the corresponding loops of RNA polymerase II (domain containing the active site of the Rpb1 subunit, PDB accession No. 16IH, see Materials and methods). The structure was generated using the software VMD (Humphrey et al., 1996).

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 code is shown on the right.
