Figure 4From: Structural characterization of a ribose-5-phosphate isomerase B from the pathogenic fungus Coccidioides immitisComparison of active site residues of eukaryotic RpiB enzymes from C. immitis (green and gray in panel A) and T. cruzi[6](salmon in panel B) and overlay in panel C. The C. immitis structure contains phosphate whereas the T. cruzi structure contains the competitive inhibitor 4-deoxy-4-phospho-D-erythronohydroxamic acid.Back to article page
