CRYSTALLIZATION (Commentary)
ORGANISM

LITERATURE
sitting-drop vapour-diffusion method by mixing 2 ml of a solution containing 11.5 mg of protein per ml with an equal volume of reservoir solution containing 0.1 M Tris hydrochloride (pH 7.2), 21% polyethylene glycol (PEG 2000 MME), and 115 mM cyclohexyl-butanoyl-N-hydroxyethylglucamide. Diffraction data are collected to a resolution of 2.2 A. The crystals belonged to space group P1 with the unit cell constants a = 63.5 A, b = 84.2 A, c = 89.1 A, alpha = 90.14°, beta = 89.9°, gamma = 76.2°, and has a solvent content of 42%
hanging drop vapor diffusion method, using 4.0 M sodium formate (pH 7.0)
hanging drop vapour diffusion method, co-crystallization with monapterin or neopterin, in 1.4 M sodium acetate, 0.2 M imidazole, 0.1 M sodium cacodylate (pH 6.5), at 19°C
in complex with neopterin, an analog of dihydroneoptierin, and with monapterin, to 1.7 A and 1.68 A resolution, respectively. Active site residues E22, K100, and Y54 function coordinately during catalysis
hanging drop vapour diffusion method with 50 mM MOPS/NaOH (pH 7.0), 17.5% (w/v) methoxy-PEG 2000, 400 mM NaCl, 10 mM MgCl2, 2 mM dithiothreitol, 1 mM EDTA and 5% (v/v) glycerol
