Equilibrium binding of single-stranded DNA with herpes simplex virus type I-coded single-stranded DNA-binding protein, ICP8.

We have carried out solution equilibrium binding studies of ICP8, the major single-stranded DNA (ssDNA)-binding protein of herpes simplex virus type I, in order to determine the thermodynamic parameters for its interaction with ssDNA. Fluorescence anisotropy measurements of a 5'-fluorescein-labeled 32-mer oligonucleotide revealed that ICP8 formed a… (More)
