Crystallization and preliminary crystallographic analysis of the DNA gyrase B protein from B. stearothermophilus.
DNA gyrase B (GyrB) from B. stearothermophilus has been crystallized in the presence of the non-hydrolyzable ATP analogue, 5'-adenylyl-beta-gamma-imidodiphosphate (ADPNP), by the dialysis method. A complete native data set to 3.7 A has been collected from crystals which belonged to the cubic space group I23 with unit-cell dimension a = 250.6 A. Self-rotation function analysis indicates the position of a molecular twofold axis. Low-resolution data sets of a thimerosal and a selenomethionine derivative have also been analysed. The heavy-atom positions are consistent with one dimer in the asymmetric unit.
