Assessment of the four methods by recovery of links between members of known E. coli protein complexes. (a) We test to see how often predicted interacting protein pairs are subunits of the same protein complex. E. coli protein complexes were obtained from the EcoCyc database. (b) Again, the ROC curve shows the performance of the rank-ordered list of all E. coli predicted interactions (solid line) compared with the random selection of protein pairs (dashed line), in their ability to recover constituents of known protein complexes.
