Figure 2. Identification of protein complexes and communities in the cellular extracts.

1. Elution of selected protein complexes as a function of their retention times (see Appendix Fig S4 for their corresponding subunit elutions).
2. Scatter plot indicating discrepancies in the expected and measured molecular weights of 102 protein complexes that elute as a single peak; 50% of protein complexes are observed to have higher molecular weights than structurally characterized, indicating that they are organized in higher‐order assemblies.
