== Publication Abstract from PubMed ==
The enzyme dihydrodipicolinate synthase catalyzes the committed step in the synthesis of diaminopimelate and lysine to facilitate peptidoglycan and protein synthesis. Dihydrodipicolinate synthase catalyzes the condensation of L-aspartate 4-semialdehyde and pyruvate to synthesize L-2,3-dihydrodipicolinate. Here, the cloning, expression, purification, crystallization and X-ray diffraction analysis of dihydrodipicolinate synthase from the pathogenic bacterium Bartonella henselae, the causative bacterium of cat-scratch disease, are presented. Protein crystals were grown in conditions consisting of 20%(w/v) PEG 4000, 100 mM sodium citrate tribasic pH 5.5 and were shown to diffract to approximately 2.10 A resolution. They belonged to space group P212121, with unit-cell parameters a = 79.96, b = 106.33, c = 136.25 A. The final R values were Rr.i.m. = 0.098, Rwork = 0.183, Rfree = 0.233.
