Substrate diversity of herpes simplex virus thymidine kinase. Impact Of the kinematics of the enzyme.

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

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...

The Effects and Pharmacokinetics of Acyclovir in Neonates

    Acyclovir (9-[2-hydroxyethoxymethyl] guanine) is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. Acycloviris converted to the monophosphate by thymidine kinase the virus-specific form of this enzyme and is subsequently converted to the triphosphate by the host cell kinase. Acyclovir triphosphate inhibits viral DNA-polymerase terminating the chain...

Substrate Diversity of Herpes Simplex Virus Thymidine Kinase

Herpes simplex virus type 1 (HSV 1) thymidine kinase (TK) exhibits an extensive substrate diversity for nucleobases and sugar moieties, in contrast to other TKs. This substrate diversity is the crucial molecular basis of selective antiviral and suicide gene therapy. The mechanisms of substrate binding of HSV 1 TK were studied by means of site-directed mutagenesis combined with isothermal calori...

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...
