Mutagenesis of a herpes simplex virus origin of DNA replication and its effect on viral interference.
Supercoiled plasmid molecules containing cloned copies of a DNA fragment which includes a functional herpes simplex virus type 1 origin of DNA replication were cleaved preferentially at two positions within the viral insert by nuclease S1. Plasmids with molecular linker insertions at these sites were constructed, and analysis of two representative plasmids demonstrated the presence of palindrom...
متن کاملHerpes simplex virus DNA replication.
The Herpesviridae comprise a large class of animal viruses of considerable public health importance. Of the Herpesviridae, replication of herpes simplex virustype-1 (HSV-1) has been the most extensively studied. The linear 152-kbp HSV-1 genome contains three origins of DNA replication and approximately 75 open-reading frames. Of these frames, seven encode proteins that are required for originsp...
متن کاملHerpes simplex viruses: mechanisms of DNA replication.
Herpes simplex virus (HSV) encodes seven proteins necessary for viral DNA synthesis-UL9 (origin-binding protein), ICP8 (single-strand DNA [ssDNA]-binding protein), UL30/UL42 (polymerase), and UL5/UL8/UL52 (helicase/primase). It is our intention to provide an up-to-date analysis of our understanding of the structures of these replication proteins and how they function during HSV replication. The...
متن کاملBinding of the herpes simplex virus type 1 UL9 gene product to an origin of viral DNA replication.
The binding of a herpes simplex virus type 1 (HSV-1) encoded polypeptide to a viral origin of DNA replication has been studied by using a gel retardation assay. Incubation of nuclear extract from HSV-1 infected cells with a labelled origin-containing fragment resulted in the formation of a specific retarded complex, the migration of which was further reduced in the presence of an antibody react...
متن کاملSequence of the putative origin of replication in the UL region of herpes simplex virus type 1 ANG DNA.
Interest has been stimulated concerning the region mapping between 0.38 and 0.42 on the prototype configuration of the herpes simplex virus type 1 (HSV-1) genome due to the high probability of the presence there of a second origin of DNA replication. A 960 bp restriction fragment (HinfI E) of a class II defective HSV-1 ANG DNA has been sequenced using the viral DNA rather than molecularly clone...
