The 1.70 angstroms X-ray crystal structure of Mycobacterium tuberculosis phosphoglycerate mutase.

The single-crystal X-ray structure of phosphoglycerate mutase from Mycobacterium tuberculosis has been determined at a resolution of 1.70 angstroms. The C-terminal tail of each of the subunits is flexible and disordered; however, for one of the four chains (chain A) all but five residues of the chain could be modeled. Noteworthy features of the structure include the active site and a proline-rich segment in each monomer forming a short left-handed polyprolyl helix. These segments lie on the enzyme surface and could conceivably participate in protein-protein interactions.
