Distributions of complex-averaged disorder of long disordered regions for complexes of different sizes. The distributions are grouped by the sizes of complexes and singular proteins for which no evidence of complex-forming has been found. Magenta - singular proteins, cyan - complexes size 2-4, orange - complexes size 5-10, blue - complexes size 11-100. The average disorder for each complex has been calculated by predicting the individual protein components, and averaging them for each complex individually by considering only residues which fall into segments longer than 30 consecutive disordered residues. Complex averages were calculated and their % distributions are presented here. Medians are indicated in parentheses. A) E. coli complexes (significantly different distributions, p-value<0.001). B) Yeast complexes (significantly different distributions, p-value<0.001).
