2.1.1.170 microbatch technique under oil at 4°C. Determination of the structure of RsmG (249 amino acids) in three different crystal forms: the enzyme in complex with the cofactor S-adensosyl-L-methionine, the enzyme in complex with S-adenosyl-L-homocysteine, the enzyme in complex with adenosine monophosphate and S-adenosyl-L-methionine. RsmG X-ray crystal structures at up to 1.5 A resolution. Cofactor-bound crystal structures of RsmG reveals a positively charged surface area remote from the active site that binds an adenosine monophosphate molecule 706725 2.1.1.170 sitting-drop vapor diffusion at 4°C against a reservoir containing 0.1 M of sodium citrate pH 6.5, 15% polyethylene glycol 4000, and 10% isopropanol 706646
