Herpes thymidine kinase
The first indirect use of thymidine kinase in biochemical research was the identification of dividing cells by incorporation of radiolabeled thymidine and subsequent measurement of the radioactivity or autoradiography to identify the dividing cells. For this purpose tritiated thymidine is included in the growth medium. In spite of errors in the technique, it is still used to determine the gro… Witryna4 kwi 2024 · Herpes simplex virus (HSV) 1 and 2 infections primarily cause oral or genital disease that is usually self-limited or resolves with antiviral therapy. ... Resistance mediated by sequence variations in the UL23 thymidine kinase gene results in absent, low production or altered activity of viral thymidine kinase, thereby preventing the …

Witryna25 maj 2024 · Definition Thymidinkinase, kurz TK, ist ein Enzym, das für den Einbau des Nukleosids Thymin in die DNA mitverantwortlich ist. Die Konzentration der Thymidinkinase wird als Maß für die Teilungsaktivität von Zellen herangezogen ( Proliferationsmarker ). Biochemie WitrynaThymidine kinases (TK) are key enzymes in the pyrimidine salvage pathway catalyzing the phosphate transfer from ATP to thymidine (dT) in the presence of Mg2+ and thus, yielding thymidine monophosphate (dTMP) and ADP. Herpesviridae, such as Herpes simplex virus type 1, encode for their own, multifunctional TK.
Witryna31 mar 2024 · True γ or γ 2 genes, unlike α, β, and γ 1 (β γ) genes of herpes simplex virus 1 (HSV-1), stringently require viral DNA synthesis for their expression. We report that γ 2 genes resident in cells were induced in trans by infection with HSV-1 but that the induction did not require amplification of either the resident gene or the infecting viral …
