Substrate specificity of Epstein-Barr virus thymidine kinase.
Purified recombinant protein encoded by the BXLF-I open reading frame of the Epstein-Barr virus genome has thymidine kinase activity. The substrate behaviors of various nucleosides toward this enzyme were tested. Halogenated deoxyuridines, zidovudine, and bromovinyldeoxyuridine are efficient substrates, while acyclovir and dihydroxypropylmethylguanine are relatively poor substrates for the Epst...
متن کاملCharacterization of an Epstein-Barr virus-induced thymidine kinase.
Previous work from our laboratory suggested that the selective inhibition of Epstein-Barr virus (EBV) replication by 1-beta-D-arabinofuranosylthymine in human lymphoid cell lines involved the induction of a new thymidine kinase (TK) able to phosphorylate the thymidine analog. We further characterized this enzyme induced in various EBV-positive cell lines after viral genome activation with a com...
متن کاملEpstein-Barr virus thymidine kinase is a centrosomal resident precisely localized to the periphery of centrioles.
The thymidine kinase (TK) encoded by Epstein-Barr virus (EBV) differs not only from that of the alphaherpesviruses but also from that of the gamma-2 herpesvirus subfamily. Because cellular location is frequently a determinant of regulatory function, to gain insight into additional role(s) of EBV TK and to uncover how the lymphocryptovirus and rhadinovirus enzymes differ, the subcellular localiz...
متن کاملIdentification and characterization of the conserved nucleoside-binding sites in the Epstein-Barr virus thymidine kinase.
Thymidine kinase (TK), encoded by EBV (Epstein-Barr virus), is an attractive target for antiviral therapy and provides a novel approach to the treatment of EBV-associated malignancies. Despite the extensive use of nucleoside analogues for the treatment of viral infections and cancer, the structure-function relationship of EBV TK has been addressed rarely. In the absence of any structural inform...
متن کاملSeropidemiology of Epstein – Barr virus infection among asymptomatic
Introduction: Epstein – Barr virus (EBV) is a herpesvirus which establishes a persistent life-long infection in over 95% of adults world wide. Infection is usually asymptomatic but the virus is associated with a variety of disease, including nasopharyngeal carcinoma (NPC), Burkitt’s lymphoma (BL), Multiple sclerosis MS, EBV-associated B-cell lymphoproliferative disease (BLPD), Hodgkin and non...
