  • cellular
  • Two different classes of thymidine kinases have been identified and are included in this super family: one family groups together thymidine kinase from herpesvirus as well as cellular thymidylate kinases, the second family groups TK from various sources that include, vertebrates, bacteria, the bacteriophage T4, poxviruses, African swine fever virus (ASFV) and Fish lymphocystis disease virus (FLDV).

  • The Prosite pattern recognizes only the cellular type of thymidine kinases. (wikipedia.org)
  • increases
  • 5'-Aminothymidine, a non-toxic analogue of thymidine, interferes with this regulatory mechanism and thereby increases the cytotoxicity of thymidine analogues used as antineoplastic drugs. (wikipedia.org)
