SINGLE STRANDED DNA-BINDING PROTEIN(ICP8) FROM HERPES SIMPLEX VIRUS-1
OverviewOverview
All organisms including animal viruses use specific proteins to bind, single-stranded DNA rapidly in a non-sequence-specific, flexible, and, cooperative manner during the DNA replication process. The crystal, structure of a 60-residue C-terminal deletion construct of ICP8, the major, single-stranded DNA-binding protein from herpes simplex virus-1, was, determined at 3.0 A resolution. The structure reveals a novel fold, consisting of a large N-terminal domain (residues 9-1038) and a small, C-terminal domain (residues 1049-1129). On the basis of the structure and, the nearest neighbor interactions in the crystal, we have presented a, model describing the site of single-stranded DNA binding and explaining, the basis for cooperative binding. This model agrees with the beaded, morphology observed in electron micrographs.
