Yes it includes the 2 complexes from the P212121 crystal form, 2 complexes from the I2 crystal form and the 4 complexes from the P32 crystal form. The close alignment of the eight separate complexes makes is a consequence of the close structural similarity. The different conformations for some side-chains of the IncE peptides in Figure 3—figure supplement 1 provide the clearest display of the eight overlaid structures.
