Abstract: | 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. Proteins 2013. © 2012 Wiley Periodicals, Inc. |
