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 bacteriumBartonella henselae, the causative bacterium of cat-scratch disease, are presented. Protein crystals were grown in conditions consisting of 20%(w/v) PEG 4000, 100 mMsodium citrate tribasic pH 5.5 and were shown to diffract to ~2.10 Å resolution. They belonged to space groupP212121, with unit-cell parametersa= 79.96,b= 106.33,c= 136.25 Å. The finalRvalues wereRr.i.m.= 0.098,Rwork= 0.183,Rfree= 0.233.
