Structural Basis for the Decarboxylation of Orotidine 5'-Monophosphate (OMP) by Plasmodium Falciparum OMP Decarboxylase
J.Biochem.(Tokyo), 143:69-78, 2008

PubMed Abstract: Orotidine 5'-monophoshate decarboxylase (OMPDC) catalyses the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP). Here, we report the X-ray analysis of apo, substrate or product-complex forms of OMPDC from Plasmodium falciparum (PfOMPDC) at 2.7, 2.65 and 2.65 A, respectively. The structural analysis provides the substrate recognition mechanism with dynamic structural changes, as well as the rearrangement of the hydrogen bond array at the active site. The structural basis of substrate or product binding to PfOMPDC will help to uncover the decarboxylation mechanism and facilitate structure-based optimization of antimalarial drugs.
