LITERATURE
purified detagged recombinant enzyme in complex with nonhydrolyzable ATP analogue, adenosine 5'-adenylyl-beta,gamma-imidodiphosphate (AMP-PNP), and with citric acid, hanging drop vapor diffusion method, mixing of 30 mg/ml protein in 50 mM Tris-HCl, pH 8.0, 0.1 M NaCl, 5 mM MgCl2, and 1 mM DTT, with an equal volume of mother liquor containing 0.4 M ammonium citrate dibasic, pH 5.0, and 21% w/v PEG 3350, soaking of crystals in 50 mM AMP-PNP, X-ray diffraction structure determination and analysis at 2.1-2.6 A resolution
the three-dimensional structure of carbamate kinase from the human parasite Giardia lamblia is determined at 3 A resolution. The crystals belong to the monoclinic space group P21, with unit-cell parameters a = 69.77, b = 85.41, c = 102.1 A, beta = 106.8°
crystals of the pyrococcal enzyme grown in the absence or presence of MgATP (Fig. 7) diffracted with a conventional X-ray source to at least 2.6 and 2.0 Å resolution, respectively
