Thymidine kinase from herpes simplex virus phosphorylates the new antiviral compound, 9-(2-hydroxyethoxymethyl)guanine.

9-(2-Hydroxyethoxymethyl)guanine (acyclo-Guo), is an effective and selective inhibitor of herpes simplex virus replication. This purine nucleoside analogue was found to be phosphorylated at a 30to 120-fold faster rate with extracts of Vero cells infected with herpes simplex virus than with extracts of uninfected cells. The enzyme responsible for this reaction was identified as the virus-coded t...

Initiation of herpes simplex virus thymidine kinase polypeptides.

When employed as a transgene reporter, the herpes simplex type 1 virus (HSV1) thymidine kinase gene (tk) is ectopically expressed in mouse testis. The principal testicular mRNA lacks the 5'-end of the tk reading frame. As a result the principal translation products, P2 and P3, are N-terminally truncated. These co-migrate in SDS-PAGE with polypeptides synthesised during HSV1 infection that were ...

Monoclonal antibodies to herpes simplex virus thymidine kinase.

Purified herpes simplex virus thymidine kinase has been used to immunize mice for the production of monoclonal antibodies to the enzyme. Monoclonal antibodies were successfully produced against both herpes simplex virus type 1 and type 2 enzymes. These antibodies should prove useful for detecting the enzyme under a variety of experimental conditions. We also demonstrate that the antibodies can ...

Structures of Thymidine kinase from Herpes simplex virus type 1 in complex with new substrates

Infections of Herpes simplex virus type 1 (HSV1) are associated with oral-facial infections, skin infections, and genital infections. During the past decade, potent agents against herpes virus infections have been found. The action of these agents is based on the difference between viral thymidine kinase (TK) and human TK. Thymidine kinase (TK, EC 2.7.1.21) is the key enzyme in the pyrimidine s...
