A MODIFIED CK2 SUBSTRATE PEPTIDE TO WHICH AN ATP-COMPETITIVE INHIBITOR MOIETY IS LINKED. ONLY THE LATTER IS DEFINED IN THE ELECTRON DENSITY WHILE THE PEPTIDIC PART IS COMPLETELY FLEXIBLE PROBABLY DUE TO ITS HIGH NEGATIVE CHARGE DENSITY.

Nine volume parts of this protein stock solution were mixed with one part 12 mM ARC-1154 dissolved in 100% dimethyl sulfoxide. The CK2alpha1-335/ARC-1154 mixture was incubated for 30 min at room temperature. The best crystals grew with a reservoir solution composed of 4.4 M NaCl, 100 mM citric acid, pH 5.25 and mixing 2 microliter of this reservoir solution with microliter CK2alpha1-335/ARC-1154 mixture, VAPOR DIFFUSION, SITTING DROP, temperature 293K
