  • PubMed Abstract: 

    Thymidylate kinase (TMPK) is a nucleoside monophosphate kinase that catalyzes the reversible phosphoryltransfer between ATP and TMP to yield ADP and TDP. In addition to its vital role in supplying precursors for DNA synthesis, human TMPK has an important medical role participating in the activation of a number of anti-HIV prodrugs.
