Frequencies of complexes with disulfide bridges. All proteins. (B) Bacterial proteins. (C) Eukaryotic proteins. SBS homomers have significantly fewer disulfide bridges than monomers, while the difference between MBS and SBS homomers is significant in the pooled data set and bacteria. (Note that the number of eukaryotic proteins is much smaller than the number of Bacterial proteins.) *p < 0.05, **p < 0.005; tests of proportions.
