LITERATURE
crystals of FTHFS complexed with NH4+, K+ or Cs+ are grown by vapor diffusion from 46% saturated ammonium sulfate, 1 mM dithiothreitol and 1% polyehtylene glycol 1000 in 50 mM potassium maleate buffer, pH 7.6, crystals diffract to 3.0-3.2 A resolution
native protein, folate complex, ADP-formylphosphate complex, and ZD9331-formylphosphate complex, hanging drop vapor diffusion method. High salt conditions contain 38-46% (w/v) saturated ammonium sulfate, 1 mM , and dithiohtreitol, 1-3.5% (w/v) PEG 1000 or PEG 1450, in 50-75 mM KMB (pH 7.0-8.0). Low salt conditions contain 18-22% (w/v) PEG 6-8K, 0.2 M ammonium sulfate, 1 mM dithiothreitol, in 75 mM KMB pH 7.0-8.5
Se-Met FTHFS is crystallized by hanging-drop vapor-diffusion, crystals diffract to 2.5 A
