thymidine kinase


thymidine kinase
Enzyme of pyrimidine salvage, catalysing phosphorylation of thymine deoxyriboside to form its 5\' phosphate, the nucleotide thymidylate. Animal cells lacking this enzyme can be selected by lethal synthesis, eg. by resistance to bromodeoxyuridine, and can be used as parentals in somatic hybridization, since they are unable to grow in HAT medium.
