Crystallization and preliminary X-ray diffraction studies on the DNA-binding domain of the multidrug transporter activation protein (MtaN) fromBacillus subtilis

The N-terminal DNA-binding domain of the multidrug transporter activation protein (MtaN) was crystallized by the hanging-drop vapour-diffusion method using lithium chloride as a precipitant. The crystals are orthorhombic and belong to the space group I2(1)2(1)2(1), with unit-cell parameters a = 49.4, b = 67.8, c = 115. 0 A. Diffraction data have been collected at 100 K to 2.75 A resolution at a synchrotron-radiation source.
