Dual binding modes: Combined empirical and computational studies of a series of compounds showed adenine and 1-benzyl-4-(dimethylamino)pyridinium fragments to function most efficiently in binding CHOKα1, and also determined how the latter fragment interacts with the choline binding site through two different binding modes. These data provide a basis for the future design of better and more selective inhibitors.

Applying a CHOK hold: Combined experimental and computational studies of the binding mode of a rationally designed inhibitor of the dimeric choline kinase α1 (CHOKα1) explain the molecular mechanism of negative cooperativity (see scheme) and how the monomers are connected. The results give insight into how the symmetry of the dimer can be partially conserved despite a lack of conservation in the static crystal structures.
