[https://www.uniprot.org/uniprot/KTHY_PLAF7 KTHY_PLAF7] Catalyzes the phosphorylation of thymidine monophosphate (dTMP) to thymidine diphosphate (dTDP), the immediate precursor for the DNA building block dTTP (PubMed:18477629, PubMed:19126267, PubMed:31934749, PubMed:20353400). Can also phosphorylate dGMP and to a lesser extent GMP, dUMP and dIMP (PubMed:18477629, PubMed:19126267, PubMed:31934749, PubMed:20353400). Can use either ATP or dATP as phosphate donors in presence of Mg(2+) (PubMed:18477629).<ref>PMID:18477629</ref> <ref>PMID:19126267</ref> <ref>PMID:20353400</ref> <ref>PMID:31934749</ref>

Plasmodium falciparum is the causative agent of malaria, a disease where new drug targets are required due to increasing resistance to current anti-malarials. TMPK (thymidylate kinase) is a good candidate as it is essential for the synthesis of dTTP, a critical precursor of DNA and has been much studied due to its role in prodrug activation and as a drug target. Type I TMPKs, such as the human enzyme, phosphorylate the substrate AZT (3'-azido-3'-deoxythymidine)-MP (monophosphate) inefficiently compared with type II TMPKs (e.g. Escherichia coli TMPK). In the present paper we report that eukaryotic PfTMPK (P. falciparum TMPK) presents sequence features of a type I enzyme yet the kinetic parameters for AZT-MP phosphorylation are similar to those of the highly efficient E. coli enzyme. Structural information shows that this is explained by a different juxtaposition of the P-loop and the azide of AZT-MP. Subsequent formation of the transition state requires no further movement of the PfTMPK P-loop, with no steric conflicts for the azide moiety, allowing efficient phosphate transfer. Likewise, we present results that confirm the ability of the enzyme to uniquely accept dGMP as a substrate and shed light on the basis for its wider substrate specificity. Information resulting from two ternary complexes (dTMP-ADP and AZT-MP-ADP) and a binary complex with the transition state analogue AP5dT [P1-(5'-adenosyl)-P5-(5'-thymidyl) pentaphosphate] all reveal significant differences with the human enzyme, notably in the lid region and in the P-loop which may be exploited in the rational design of Plasmodium-specific TMPK inhibitors with therapeutic potential.
