Webb26 aug. 2011 · There are two distinct pathways for thymidine nucleotide synthesis ( Fig. 1 ). The salvage pathway involves the conversion of thymidine to thymidylate, and occurs in the mitochondria and cytoplasm catalyzed by TK2 and thymidine kinase 1 (TK1), respectively ( 7 ). WebbHAT stands for Hypoxanthine Aminopterin Thymidine. The Hypoxanthine and Thymidine are the bases which are converted into nucleotides by the enzymes HGPRTase and Thymidine kinase respectively. The pathway of nucleotide synthesis, which involves these two key enzymes is known as the salvage pathway.

WebbPathway for TTP synthesis. The key intermediate is dUTP, which is converted to dUMP by dUTPase. Because there is only one pathway for synthesis of TMP, it can be used to synthesize radioactively labeled DNA or to inhibit DNA synthesis selectively. 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…

WebbThymidine kinases have a key function in the synthesis of DNA and therefore in cell division, as they are part of the unique reaction chain to introduce thymidine into the DNA. Thymidine is present in the body fluids as a result of degradation of DNA from food and from dead cells. Thymidine kinase is required for the action of many antiviral drugs.
