Inducibility of Thymidine Kinase by Thymidine as a Function of Interphase Stage
Thymidine may act as an inducer of thymidine kinase activity in cells of higher plants. The general response is demonstrable in a randomly developing cell population such as is found in germinating wheat embryos. If a synchronously developing cell population is studied, however, potentially inducible cells are found to be susceptible to the inductive effect of thymidine only during about 10 per...
متن کاملFeedback Inhibition of Thymidine Kinase by Thymidine Triphosphate.
That the regulation of cell division and deoxyribonucleic acid synthesis is subject to some kind of chemical control in higher organisms is widely accepted (2-5). Davidson (2) has suggested that deoxyribonucleic acid synthesis takes place at critical concentrations of the deoxyribonucleoside triphosphates and that these compounds are components of a homeostatic mechanism. There are now at least...

متن کاملRegulation and biological function of thymidine kinase.
Introduction Thymidine kinase (TK) is an enzyme of the salvage pathway of nucleotide biosynthesis. There are only a few organisms (yeast being one of them) that do not have at least one enzyme of this specificity. Also most DNA viruses, from bacteriophages to human pathogenic viruses such as herpes and vaccinia, code for TKs [l]. Some of these viral TKs are of special interest; they are useful ...
متن کاملHuman Thymidine Kinase
Cytosolic thymidine kinase (EC 2.7.1.21) has been purified 5200-fold to apparent homogeneity from normal human placenta. The purification includes sequential affinity chromatography on blue-Sepharose and a thymidine column. The molecular weight of the enzyme determined by gel filtration and sucrose density ultracentrifugation is 92,000. The subunit molecular weight is 44,000, suggesting that t...
