2.7.11.1 - 491320, 491614, 762489 2.7.11.1 autoinhibitory junction region bound to the calmodulin-like domain and Ca2+, 20 mg/ml protein in 20 mM Tris buffer, pH 7.0, 10 mM CaCl2, 10 mM DTT, mixed with an equal volume of precipitating agent composed of 15% w/v PEG 400, 0.1 M calcium chloride, and 0.1 M sodium acetate at pH 7.6, equilibration against a reservoir of precipitating agent by vapour diffusion at 20°C, X-ray diffraction structure determination and anaylsis at 2.0 A resolution, multiple-wavelength anomalous dispersion 675373 2.7.11.1 crystallized by vapour diffusion method. Crystal structure, at 2.1 A resolution, of recombinant alpha subunit of protein kinase CK2a in the presence of ATP and Mg2+, shows the enzyme in an active conformation stabilized by interactions of the N-terminal region with the activation segment and with a cluster of basic residues known as the substrate recognition site. The active centre is occupied by a partially disordered ATP molecule with the adenine base attached to a novel binding site of low specificity. This finding explains the observation that CK2, unlike other protein kinases, can use both ATP and GTP as phosphorylating agents 727360 2.7.11.1 hanging drop vapor diffusion in 1 ml wells containing 5–12% poly(ethylene glycol) 900 and 100 mM sodium phosphate/citrate buffer, pH 3.6–4.1.
