Figure 9From: SeqX: a tool to detect, analyze and visualize residue co-locations in protein and nucleic acid structuresAtomic distances in a protein structure of two parallel alpha helices. Distances between C-α atoms are indicated around ILE88. The distance to the -4th ARG84is 6.2 A and to the +4th GLU92 is 6.0 A. This indicates that Ex. +/- 4 might be necessary to exclude the aspecific neighbor effects.Back to article page
