Native/decoy similarity. When superposed using the program SAP, both N-terminal (left) and C-terminal (right) domains have some degree of similarity to their reversed decoy ‘doppleganger’, which is more marked for the N domain. The superposed structures are coloured by the SAP residue-level score as red = high similarity, blue = low. The N domain has roughly 60 equivalent α-carbon positions compared to only 24 in the larger C domain. a N. b C
