Crystallization and preliminary X-ray diffraction analysis of dihydrodipicolinate synthase 2 from Arabidopsis thaliana

Dihydrodipicolinate synthase (DHDPS; EC 4.2.1.52) catalyzes the first committed step of the lysine-biosynthetic pathway in plants and bacteria. Since (S)-lysine biosynthesis does not occur in animals, DHDPS is an attractive target for rational antibiotic and herbicide design. Here, the cloning, expression, purification, crystallization and preliminary X-ray diffraction analysis of DHDPS2 from Arabidopsis thaliana are reported. Diffraction-quality protein crystals belonged to space group P2₁2₁2.
