The major herpes simplex virus DNA-binding protein, ICP8, was purified from cells infected with the herpes simplex virus type 1 temperature-sensitive strain tsHA1. tsHA1 ICP8 bound single-stranded DNA in filter binding assays carried out at room temperature and exhibited nonrandom binding to single-stranded bacteriophage fd DNA circles as determined by electron microscopy. The filter binding assay results and the apparent nucleotide spacing of the DNA complexed with protein were identical, within experimental error, to those observed with wild-type ICP8. Thermal inactivation assays, however, showed that the DNA-binding activity of tsHA1 ICP8 was 50% inactivated at approximately 39 degrees C as compared with 45 degrees C for the wild-type protein. Both wild-type and tsHA1 ICP8 were capable of stimulating viral DNA polymerase activity at permissive temperatures. The stimulatory effect of both proteins was lost at 39 degrees C.
