XometC, a cystathionine γ-lyase-like protein from X. oryzae pv. oryzae and an antibacterial drug-target protein against bacterial blight, was cloned, purified and crystallized. Preliminary X-ray crystallographic analysis of XometC crystals was carried out. Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial blight of rice (Oryza sativa L.), one of the most devastating diseases of rice in most rice-growing countries. XometC, a cystathionine γ-lyase (CGL) like protein that is an antibacterial drug-target protein against Xoo, was cloned, expressed, purified and crystallized. CGL catalyzes the second step in the reverse-transsulfuration pathway, which is essential for the metabolic interconversion of the sulfur-containing amino acids cysteine and methionine. Crystals of two different shapes, plate-shaped and pyramid-shaped, diffracted to 2.9 and 3.2 Å resolution and belonged to the primitive orthogonal space group P2{sub 1}2{sub 1}2{sub 1} and the tetragonal space group P4{sub 1} (or P4{sub 3}), with unit-cell parameters a = 73.0, b = 144.9, c = 152.3 Å and a = b = 78.2, c = 300.7 Å, respectively. For the P2{sub 1}2{sub 1}2{sub 1} crystals, three or four monomers exist in the asymmetric unit with a corresponding V{sub M} of 3.02 or 2.26 Å{sup 3} Da{sup −1} and a solvent content of 59.3 or 45.7%. For the P4{sub 1} (or P4{sub 3}) crystals, four or five monomers exist in the asymmetric unit with a corresponding V{sub M} of 2.59 or 2.09 Å{sup 3} Da{sup −1} and a solvent content of 52.5 or 40.6%.
