From: Search for allosteric disulfide bonds in NMR structures
Mean distance between the α-carbons of each of the 20 disulfide configurations in NMR and X-ray structures. The mean distance between the α carbons of all disulfides is 5.6 Å for both NMR (part A) and X-ray (part B) structures. The outliers with a short α carbon distance are the allosteric -RHStaple bonds in both NMR and X-ray structures and the -LHStaple bonds in NMR structures. The dotted lines are the linear least-squares fit to the data.
