    Decaprenylphosphoryl-β-D-ribose 2'-epimerase (DprE1) is an essential enzyme in the biosynthesis of cell wall components and a target for development of anti-tuberculosis drugs. We determined the crystal structure of a truncated form of DprE1 from Mycobacterium smegmatis in two crystal forms to up to 2.35 Å resolution. The structure extends from residue 75 to the C-terminus and shares homology with FAD-dependent oxidoreductases of the vanillyl-alcohol oxidase family including the DprE1 homologue from M. tuberculosis. The M. smegmatis DprE1 structure reported here provides further insights into the active site geometry of this tuberculosis drug target.
