Figure 3.

Density evidence for structural disorder. The pairs of overlapping molecules 0A, 0B and 5A, 5B are shown in red and blue, respectively. Score OMIT maps around molecules A and B are shown in grey and black, respectively. (a) Score OMIT 2F _o − F _c map around the helices of tetramers 0A and 0B. The score OMIT map was calculated by omitting both overlapping tetramers 0A and 0B. (b) Score OMIT F _o − F _c map for intersecting strands of molecule 0. The OMIT maps were calculated by omitting the 0A and 0B tetramers/molecules separately and were combined into one image.
