Crystal structure of human uracil-DNA glycosylase in complex with a protein inhibitor: protein mimicry of DNA.

Uracil-DNA glycosylase inhibitor (Ugi) is a B. subtilis bacteriophage protein that protects the uracil-containing phage DNA by irreversibly inhibiting the key DNA repair enzyme uracil-DNA glycosylase (UDG). The 1.9 A crystal structure of Ugi complexed to human UDG reveals that the Ugi structure, consisting of a twisted five-stranded antiparallel beta sheet and two alpha helices, binds by inserting a beta strand into the conserved DNA-binding groove of the enzyme without contacting the uracil specificity pocket. The resulting interface, which buries over 1200 A2 on Ugi and involves the entire beta sheet and an alpha helix, is polar and contains 22 water molecules. Ugi binds the sequence-conserved DNA-binding groove of UDG via shape and electrostatic complementarity, specific charged hydrogen bonds, and hydrophobic packing enveloping Leu-272 from a protruding UDG loop. The apparent mimicry by Ugi of DNA interactions with UDG provides both a structural mechanism for UDG binding to DNA, including the enzyme-assisted expulsion of uracil from the DNA helix, and a crystallographic basis for the design of inhibitors with scientific and therapeutic applications.

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.
