SB2010 Docking Database [2010.05.19 Initial Release]
The base version of the database is presented as Receptors, Ligands and Spheres, which is applicable to any docking program. The spheres and grids are meant to be used with any version of the DOCK program.
SB2010 is an on-going project; more structures and related resources will be added in the future. The Unbiased Ligand Structures were arbitrarily translated and rotated from the binding, and minimized in the absence of the receptor.

SB2010 Ligand Flexibility Subsets
The Flexibility Subset Lists divide the database into three subsets to allow benchmarking of docking programs across three ligand flexibility ranges.

Unbiased Ligands
In the regular testset distribution, the ligand provided is the native crystal structure pose. In order to test if starting with the correct conformation initially biased the results of flexible docking experiments, we also provide 'unbiased' ligands.
$system.lig.am1bcc.unbiased_gasmin.mol2 is minimized in gas phase with the MMFF94x forcefield with the MOE 2009.10 program. $system.lig.am1bcc.unbiased_gasmin.trans.mol2 is the same minimized molecule, rigid-body translated and rotated (transformed) from the starting coordinates by about 15A.
