Kinetic studies with N2-phenylguanines and with L-thymidine indicate that herpes simplex virus type-1 thymidine kinase and thymidylate kinase share a common active site.

PCR detection of thymidine kinase gen of latent herpes simplex Virus type 1 in mice trigeminal ganglia

  Herpes simplex virus type 1 establishes a latent infection in the peripheral nervous system following primary infection. During latent infection, virus genome exhibit limited transcription, with the HSV LATs consistently detected in latency infected ganaglia. Following ocular infection viral latency develops in the trigeminal ganglia. In this study PCR has been used for detection of HSV-1 nuc...

Restriction Enzyme Analysis of Thymidine Kinase Gene in Four Iranian Isolates of Herpes Simplex Virus Type 1

Kinetic studies of herpes simplex virus type 1-encoded thymidine and thymidylate kinase, a multifunctional enzyme.

Kinetic studies of the reactions catalyzed by herpes simplex virus type l-encoded thymidine and thymidylate multifunctional kinase indicate that the addition of substrates (thymidine and ATP*Mg’+, or thymidylate and ATP l Mg2+) to the enzyme is random, while release of the products (thymidylate and ADP*M8+, or thymidine diphosphate and ADP*Mg+) is ordered, with ADP.Mg2+ being released first. Th...

In vitro Interaction of HSV-1 ORF P with Both Thymidine Kinase (TK) and an Unidentified Cellular Protein

Herpes simplex virus type-1 (HSV-1) is a neurotropic pathogen of humans that establishes latent infection in the sensory ganglia innervating the site of primary infection. A number of genes control HSV-1 pathogenicity and latency. Open reading frame P (ORF P) is one of these genes that might have a role in latency and pathogenesis. A complication in the analysis of the role of ORF P in the HSV-...

Comparative Molecular PCR-RFLP Study of Native Herpes Simplex Virus Type 1 (HSV-1) with KOS Strain

Background: Recent research on several DNA fragments covering open reading frames (ORF) 1-37 shows a new genetic marker in ORF 6 which is specific for differentiating wild-type varicella-zoster virus (VZV) strains from Oka varicella vaccine strain. On the other hand, herpes simplex virus (HSV) genome analysis by restriction enzymes is used to differentiate types one and two of the virus and eve...
