Fingerprints of difference density. (a) Correlation of each of 119 unique ligands after fitting to difference density for tris-(hydroxyamino)-methane from PDB entry 1m6z (A. Noergaard, P. Harris, S. Larsen & H. E. M. Christensen, unpublished work) at a resolution of 1.4 Å. The ligands are sorted from left to right based on increasing numbers of non-H atoms. (b) As in (a), except fitting to difference density for ATP from PDB entry 1aq2 at a resolution of 1.9 Å (Tari et al., 1997 ▶). The correlations are all indicated by filled triangles, except for the correlation of the correct ligand, which is indicated by an open diamond.
