CRYSTAL STRUCTURE OF NIMA FROM D. RADIODURANS
Overview
5-Nitroimidazole-based antibiotics are compounds extensively used for, treating infections in humans and animals caused by several important, pathogens. They are administered as prodrugs, and their activation depends, upon an anaerobic 1-electron reduction of the nitro group by a reduction, pathway in the cells. Bacterial resistance toward these drugs is thought, to be caused by decreased drug uptake and/or an altered reduction, efficiency. One class of resistant strains, identified in Bacteroides, has, been shown to carry Nim genes (NimA, -B, -C, -D, and -E), which encode for, reductases that convert the nitro group on the antibiotic into a, non-bactericidal amine. In this paper, we have described the crystal, structure of NimA from Deinococcus radiodurans (drNimA) at 1.6 A, resolution. ... [(full description)]
