THE STRUCTURAL BASIS OF SPECIFIC BASE EXCISION REPAIR BY URACIL-DNA GLYCOSYLASE
Overview
The 1.75-A crystal structure of the uracil-DNA glycosylase from herpes, simplex virus type-1 reveals a new fold, distantly related to, dinucleotide-binding proteins. Complexes with a trideoxynucleotide, and, with uracil, define the DNA-binding site and allow a detailed, understanding of the exquisitely specific recognition of uracil in DNA., The overall structure suggests binding models for elongated single- and, double-stranded DNA substrates. Conserved residues close to the, uracil-binding site suggest a catalytic mechanism for hydrolytic base, excision.
