Crystal Structure of the apo-form of orotidine-5'-monophosphate decarboxylase from P.falciparum
Overview
Summary Orotidine 5'-monophoshate decarboxylase (OMPDC) catalyzes 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.
