Bacillus anthracis is the causative agent of the deadly disease Anthrax. Its use in bioterrorism and its ability to re-emerge have brought renewed interest in this organism. B. anthracis is a Gram-positive bacterium that adds L-rhamnose to its cell-wall polysaccharides using the activated donor dTDP-β-L-rhamnose. The enzymes involved in the biosynthesis of the activated donor are absent in humans, which make them ideal targets for therapeutic development to combat pathogens. Here, the 2.65 Å resolution crystal structure of the fourth enzyme in the dTDP-β-L-rhamnose-biosynthetic pathway from B. anthracis, dTDP-4-dehydro-β-L-rhamnose reductase (RfbD), is presented in complex with NADP + . This enzyme catalyzes the reduction of dTDP-4-dehydro-β-L-rhamnose to dTDP-β-L-rhamnose. Although the protein was co-crystallized in the presence of Mg 2+ , the protein lacks the conserved residues that coordinate Mg 2+ .
