For cases where cofactors interact with the ligand in a given complex, examples of CANDOCK successfully reproducing the crystal pose are given in Figure to showcase the versatility of the CANDOCK algorithm. In Figure -b the energy minization procedure moved the location of the Zn 2+ ion in the binding pocket. This movement does not prevent the algorithm from producing a pose within 2.0 Å of the native pose and can be explained by the repulsive part of the minization potential being too extreme (Figure ). The docked pose of compounds that interact with a zinc ion through a sulfonyl amide group are shown in Figure . For the compound in Figure , the orientation of the sulfonyl amide aligns perfectly with the reference pose. For the compound in Figure , the docked pose of the same group does not align with its reference; however, the overall pose still is within 2.0 Å of this reference. Therefore, the ability for CANDOCK to produce a pose within 2.0 Å of the reference is not dependent on correctly predicting the orientation of all functional groups in a given molecule.
