Examples of built loops. Newly built parts are shown in pink. (a) 3abz chain B residues 497–510. The RSCC for this loop is 0.76; in OMIT map it is 0.55. (b) 5iro chain I residues 243–249. RSCC values (normal/OMIT) are 0.84 and 0.98. (c) 2amj chain D residues 108–117. RSCC values (normal/OMIT) are 0.80 and 0.61. Details described in the main text. The 2mF o − DF c maps are shown at 0.8, 1.2 and 1.0σ, respectively. The mF o − DF c maps are shown at 3.0σ in all cases.
