N-Succinyldiaminopimelate aminotransferase from Mycobacterium tuberculosis (DAP-AT; DapC; Rv0858c) has been cloned, heterologously expressed in Escherichia coli, purified using standard chromatographic techniques and crystallized in two related crystal forms. Preliminary diffraction data analysis suggests the presence of a monomer in the asymmetric unit of the tetragonal crystal form and a dimer in the asymmetric unit of the orthorhombic crystal form.
