In ICP8, the herpes simplex virus (HSV-1) single-strand DNA-binding protein (ssDNA-binding protein (SSB)), the head consists of the eight alpha helices.The front side of the neck region consists of a five-stranded beta-sheet and two alpha helices, whereas the back side is a three-stranded beta-sheet The shoulder part of the N-terminal domain contains an alpha-helical and beta-sheet region.

ICP8, the herpes simplex virus type-1 single-strand DNA-binding protein, is one of seven proteins encoded in the viral genome of HSV-1 that is required for HSV-1 DNA replication. [1] It is able to anneal to single-stranded DNA ( ssDNA ) as well as melt small fragments of double-stranded DNA (dsDNA); [ 1 ] its role is to destabilize duplex DNA ...
All members of the Herpesviridae share a common structure; a relatively large, monopartite, double-stranded, linear DNA genome encoding 100–200 genes encased within an icosahedral protein cage (with T=16 symmetry) called the capsid, which is itself wrapped in a protein layer called the tegument containing both viral proteins and viral mRNAs ...
Common infections in humans caused by members of this order include cold sores, genital herpes, chickenpox, shingles, and glandular fever. Herpesvirales is the sole order in the class Herviviricetes, which is the sole class in the phylum Peploviricota.
Herpes virus DNA contains a gene for a protein called ICP4, which is an important transactivator of genes associated with lytic infection in HSV-1. [47] Elements surrounding the gene for ICP4 bind a protein known as the human neuronal protein neuronal restrictive silencing factor (NRSF) or human repressor element silencing transcription factor ...
Generic HUH endonuclease binding to single-stranded DNA. HUH endonucleases (HUH-tags) are sequence-specific single-stranded DNA (ssDNA) binding proteins originating from numerous species of bacteria and viruses. [1] Viral HUH endonucleases are involved in initiating rolling circle replication while ones of bacterial origin initiate bacterial ...
WASHINGTON (Reuters) -The number of Americans filing new applications for jobless benefits fell more than expected last week, reversing the prior week's jump and suggesting that a gradual labor ...
During the rolling circle replication, the ssDNA of geminivirus is converted to dsDNA and Rep is then attached to the dsDNA at the origin sequence TAATATTAC. After Rep, along with other replication proteins, binds to the dsDNA it forms a stem loop where the DNA is then cleaved at the nanomer sequence causing a displacement of the strand.
