Crystal structure of restriction endonuclease BglI bound to its interrupted DNA recognition sequence.
M.Newman, K.Lunnen, G.Wilson, J.Greci, I.Schildkraut, S.E.Phillips.
The crystal structure of the type II restriction endonuclease BglI bound to DNA containing its specific recognition sequence has been determined at 2.2 A resolution. This is the first structure of a restriction endonuclease that recognizes and cleaves an interrupted DNA sequence, producing 3' overhanging ends. BglI is a homodimer that binds its specific DNA sequence with the minor groove facing the protein. Parts of the enzyme reach into both the major and minor grooves to contact the edges of the bases within the recognition half-sites. The arrangement of active site residues is strikingly similar to other restriction endonucleases, but the co-ordination of two calcium ions at the active site gives new insight into the catalytic mechanism. Surprisingly, the core of a BglI subunit displays a striking similarity to subunits of EcoRV and PvuII, but the dimer structure is dramatically different. The BglI-DNA complex demonstrates, for the first time, that a conserved subunit fold can dimerize in more than one way, resulting in different DNA cleavage patterns.

Figure 1.
Figure 1 Sequence of the 17 base pair DNA fragment used in the BglI -DNA complex. Recognition half-sites are boxed. The sites of cleavage are indicated by arrows. The position of the crystallographic two-fold is shown and the symmetry related strand is indicated by #. To avoid crystallographic disorder, an A:A mismatch was incorporated at the centre of the oligonucleotide.

Figure 5 The active site of BglI. (A) Comparison of the active sites of BglI and EcoRV. Both views are in a similar orientation and show similar regions of the structures. The central -sheet is green with an -helix ( 4 in BglI and B in EcoRV) is purple. Only five bases of a single strand of DNA are shown for clarity, with the sugar -phosphate backbone in red. Active site residues and the active site phosphate are shown as a ball-and-stick representation. Calcium ion positions for the BglI -DNA complex are shown as cyan spheres. (B) Stereo view of the co-ordination geometry of the Ca^2+ ions in the active site of BglI. Active site residues are shown as a ball-and-stick representation. Only a small segment of the DNA phosphate backbone on either side of the scissile phosphodiester bond is shown. DNA bases have been omitted for clarity. Calcium ions are shown as cyan spheres. Atoms co-ordinated to the calcium ions are shown connected by solid grey lines. (C) The active site of the 3' -5' exonuclease domain of DNA polymerase I (PDB code 1kfs) shown as a ball-and-stick representation. Divalent cations, shown as cyan spheres, are Zn2+ at position 1 and Mg2+ at position 2. The attacking water molecule is not shown. Produced using MOLSCRIPT (Kraulis, 1991) and RASTER3D (Merritt and Murphy, 1994).

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.
