Abstract:
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 P2(1)2(1)2.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
