loop_ _atom_sites_alt_ens.id _atom_sites_alt_ens.details 'Ensemble 1-A' ; The inhibitor binds to the enzyme in two, roughly twofold symmetric, alternative conformations. This conformational ensemble includes the more populated conformation of the inhibitor (id=1) and the amino acid side chains and solvent structure that correlate with this inhibitor conformation. Also included are one set (id=3) of side chains with alternative conformations when the conformations are not correlated with the inhibitor conformation. ; 'Ensemble 1-B' ; The inhibitor binds to the enzyme in two, roughly twofold symmetric alternative conformations. This conformational ensemble includes the more populated conformation of the inhibitor (id=1) and the amino acid side chains and solvent structure that correlate with this inhibitor conformation. Also included are one set (id=4) of side chains with alternative conformations when the conformations are not correlated with the inhibitor conformation. ; 'Ensemble 2-A' ; The inhibitor binds to the enzyme in two, roughly twofold symmetric alternative conformations. This conformational ensemble includes the less populated conformation of the inhibitor (id=2) and the amino acid side chains and solvent structure that correlate with this inhibitor conformation. Also included are one set (id=3) of side chains with alternative conformations when the conformations are not correlated with the inhibitor conformation. ; 'Ensemble 2-B' ; The inhibitor binds to the enzyme in two, roughly twofold symmetric alternative conformations.
