Extended Data Fig. 6: Structural analysis of the HD of the OsSOS1.
From: Structure and activation mechanism of the rice Salt Overly Sensitive 1 (SOS1) Na+/H+ antiporter
(a) Ribbons drawing and domain topology of the OsSOS1 HD, with one protomer in green and the other in grey. (b) Electrostatic potential at helical domain surface. Electronegative and electropositive potential are colored in degrees of red and blue saturation, respectively. One protomer is drawn as ribbon diagram, and colored in green. Highly conserved charged residues at the dimeric HD interface and ion-conducting pathway are shown in stick. Two conserved glycine-mediate kinks, H6 (~35°) and H7 (~34°), are indicated.
