Fig. 2. The twisted two-layer architecture of the GmALMT12/QUAC1 channel.

Fig. 2.

(A) Dimeric interfaces of TMD and CHD of the GmALMT12/QUAC1 channel. These dimeric interfaces are nearly perpendicular to each other, forming a dihedral angle of ~83°. The ribbon model is colored as in Fig. 1A. (B) Layer interface between TMD and CHD. The TMD portion connects to the CHD portion via a highly conserved PXWXG motif (P218-N219-W220-S221-G222, in salmon), which interacts with another characteristic motif WEP (W288-E289-P290, located between helices H2 and H3, in blue). Other surrounding charged residues at the interface are also shown in sticks, including R56, R291, R294, D54, E223, D224, and E289. The ribbon model is colored as in (A).
