G5–E and E–G5 interfaces in SasG. G5 and E domains are shown in red and blue, respectively. (A) Schematic representation of the interfaces indicating the similarity between the N- and C-terminal sheets of each domain. (B) Structural representation of the interfaces showing the equivalent residues involved in interdomain interactions. (C) Structural representation of the interfaces highlighting the major difference between G5–E and E–G5 (stereo images showing a portion of electron density are shown in Fig. S4).
