1-(5-O-Phosphono-2,3-dideoxy-β-D-glycero-penta-2-enofuranosyl)-5-methyl-1,2,3,4-tetrahydropyrimidine-2,4-dione

3`-Deoxy-5`-thymidylic Acid has been shown to complex with human thymidylate kinase via hydrogen bonding between Arg97 residues and phosphate groups. This interaction leads to the closed P-loop conformation in human thymidylate kinase, which promotes phosphorylation of nucleotides and has the potential as a model for novel compounds as a result of structure-based design studies.
