The crystallization of PfOMPDC with substrate bound represents an important advance for structure-based drug-design efforts [Tokuoka et al. (2008), J. Biochem. 143, 69-78]. The complex of the enzyme bound to the substrate OMP (PDB entry 2za1) would be of particular utility in this regard. However, re-refinement of this structure of the Michaelis complex shows that the bound ligand is the product rather than the substrate. Here, the re-refinement of a set of three structures, the apo enzyme and two versions of the product-bound form (PDB entries 2za1, 2za2 and 2za3), is reported. The improved geometry and fit of these structures to the observed electron density will enhance their utility in antimalarial drug design. Re-refinement of Plasmodium falciparum orotidine 5'-monophosphate decarboxylase provides a clearer picture of an important malarial drug target.,Novak WRP, West KHJ, Kirkman LMD, Brandt GS Acta Crystallogr F Struct Biol Commun. 2018 Oct 1;74(Pt 10):664-668. doi:, 10.1107/S2053230X18010610.
