== Publication Abstract from PubMed ==
 +
The 60-fold reduced phosphorylation rate of azidothymidine (AZT) monophosphate (AZTMP), the partially activated AZT metabolite, by human thymidylate kinase (TMPK) severely limits the efficacy of this anti-HIV prodrug. Crystal structures of different TMPK nucleotide complexes indicate that steric hindrance by the azido group of AZTMP prevents formation of the catalytically active closed conformation of the P-loop of TMPK. The F105Y mutant and a chimeric mutant that contains sequences of the human and Escherichia coli enzyme phosphorylate AZTMP 20-fold faster than the wild-type enzyme. The structural basis of the increased activity is assigned to stabilization of the closed P-loop conformation.
