Differences in database retrieval performance of AASurf and backbone representations. The graph at the bottom shows the precision-recall AUC difference of AASurf to CACNO. The positive value indicates that the AASurf has a better performance. Four proteins are shown as examples. The first two, PDB:1tme1 in Group 25 (G25) and PDB:1r1a3 in G65 are examples where AASurf shows a better performance, while the latter two, PDB:1rtwA in G102 and PDB:1bio in G124 are cases where CACNO performs better. 1tme1 has the AUC difference of 0.0656, the sphericity (sp) of -0.104, and has 8 residues further than two times of the radius of gyration from the center. 1r1a3: AUC difference: 0.146, sp: -0.199, and 5 tail-like residues. 1rtwA, the AUC difference: -0.387, sp: 0.152, and no tail residues 1bio, the AUC difference: -0.597, sp: 0.165, and no tail residues.
