Structure of Ldt_Mt2, an L,D-transpeptidase from Mycobacterium tuberculosis

The crystal structures of two fragments of the L,D-transpeptidase from M. tuberculosis have been determined at 1.45 and 1.86 Å resolution. The extramembrane part of this enzyme consists of three domains: two domains related to the immunoglobulin fold and a catalytic domain belonging to the ErfK/YbiS/YhnG family at the C-terminus.
