Abstact

The key enzyme in the nonmevalonate pathway, 1-deoxy-D-xylulose 5-phosphate reductoisomerase (DXR), has been shown to be an effective target of antimalarial drugs. Here we report the crystal structure of DXR complexed with NADPH and a sulfate ion from Escherichia coli at 2.2 A resolution. The structure showed the presence of an extra domain, which is absent from other NADPH-dependent oxidoreductases, in addition to the conformation of catalytic residues and the substrate binding site. A flexible loop covering the substrate binding site plays an important role in the enzymatic reaction and the determination of substrate specificity.
