Superposition of EFE-b with EFE-a and trypsin. (a) Stereoview of the superposition of EFE-b with EFE-a is illustrated as follows: EFE-b is represented by green and EFE-a by light goldenrod yellow. The glycan is represented by a ball-and-stick model (carbon atoms, green). Some loops in which EFE-b greatly differs from EFE-a are indicated: loop A (34–41); loop C (97–103); loop 2 (217–225); loop 3 (169–174); loop 4 (201–208). (b) Stereoview of the superposition of EFE-b with trypsin is illustrated as follows: EFE-b is represented by green and trypsin (Protein Data Bank, accession number, 1PPE) by orange. The glycan is represented by a ball-and-stick model (carbon atoms, green) (see [56]).
