Cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of DapA (Rv2753c) from Mycobacterium tuberculosis

Journal Article · · Acta Crystallographica. Section F
M. tuberculosis dihydrodipicolinate synthase, the enzyme that catalyzes the first unique reaction in the l-lysine biosynthesis pathway, has been cloned, expressed, purified and crystallized and the crystals have been characterized by X-ray diffraction. Dihydrodipicolinate synthase from Mycobacterium tuberculosis (DHDPS, DapA, Rv2753c) has been cloned, heterologously expressed in Escherichia coli, purified using standard chromatographic techniques and crystallized in a monoclinic crystal form. Preliminary diffraction data analysis suggests the presence of two independent tetramers in the asymmetric unit in almost the same relative orientation.
