(a) Fo − Fc difference density for NAG-NAG-MAN (PDB entry 1d7d
, 1.95 Å; Hallberg et al., 2000) fitted beginning with the same ligand from a different PDB entry. (b) The same map fitted beginning with ligands from five different PDB entries. (c) R.m.s.d. of fits beginning with NAG-NAG-MAN from 74 different PDB entries to the original ligand in PDB entry 1d7d
and correlation coefficient of fitted ligand to the difference density map. (d) Histogram of r.m.s.d. of fits from (c). |
