== Publication Abstract from PubMed ==
The Bacillus subtilis bacteriophages PBS-1 and PBS-2 protect their uracil-containing DNA by expressing an inhibitor protein (UGI) which inactivates the host uracil-DNA glycosylase (UDGase) base-excision repair enzyme. Also, PBS1/2 UGI efficiently inactivates UDGases from other biological sources, including the enzyme from herpes simplex virus type-1 (HSV-1). The crystal structure of the HSV-1 UDGase-PBS1 UGI complex at 2.7 angstrum reveals an alpha-beta-alpha sandwich structure for UGI which interacts with conserved regions of UDGase involved in DNA binding, and directly mimics protein-DNA interactions observed in the UDGase-oligonucleotide complex. The inhibitor completely blocks access to the active site of UDGase, but makes no direct contact with the uracil-binding pocket itself.
