Process of “blurring”, that is, systematically perturbing
the ligand within the protein binding pocket, shown for n-butyl benzene (186L). (a) Before blurring, single conformation in
the binding pocket. (b) After blurring, numerous conformations superimposed
in the binding pocket: front view, (c) side view. Carbon atoms are
displayed in gray and hydrogen atoms in white while red symbolizes
oxygen and blue represents nitrogen.
