6.2.1.33	hanging drop vapor diffusion method, 1.0 and 2.2 A. Crystal structures of the enzyme both in the unliganded state and bound to 4-chlorobenzoate. The space group is P3(1)21 or P3(2)21 with a = b = 129.3 A, c = 71.5 A	
6.2.1.33	mutant D402P, to 2.6 A resolution, and comparison with wild-type. The C-terminal domain rotates by about 140 degrees between the two states that catalyze the adenylation and thioester-forming half-reactions. The domain rotation is accompanied by a change in the main chain torsional angles of residue D402	
6.2.1.33	purified recombinant CBL bound to 4-chlorobenzoyl-AMP, hanging drop vapor diffusion at 4°C using 16-24% pentaerythritol propoxylate 426, and 0.1 M K+-HEPES, pH 6.5 or 6.75, and optimized via hanging drop vapor diffusion using 14-18% PEG 1000, 50-100 mM magnesium nitrate and 100 mM MOPS, pH 7.0, the cryoprotectant contains 24% pentaerythritol propoxylate 426, 24% ethylene glycol, and 0.1 M K+-HEPES, 1 mM ATP, and 1 mM 4-chlorobenzoate, X-ray diffraction structure determination and analysis at 2.0-2.25 A resolution, molecular replacement	
6.2.1.33	purified recombinant enzyme, X-ray diffraction structure determination and analysis, modelling
