Figure 1
The separation between self-vectors and cross-vectors as a function of vector length (radius from the Patterson origin) for some example structures. In each case, the solid line is the number of self-vectors, the dashed line is the number of cross-vectors and the dotted line is the self/cross vector ratio. (a) A small protein, 119 residues, size ∼23 × 23 × 50 Å, space group P212121, PDB code 1gyu
. (b) A larger heterotetramer, 1730 residues, ∼80 × 80 × 100 Å, space group P3121, PDB code 1gw5
. (c) An elongated monomer, 217 residues, ∼25 × 25 × 110 Å, space group P3121, PDB code 1uru
. (d) The equivalent dimer, 434 residues, ∼25 × 25 × 145 Å, calculated in space group P31. |
