Fig. 4: Ion-conducting pathway.
From: Mechanosensitive channel YnaI has lipid-bound extended sensor paddles

a The calculated ion-conducting pathway (green) shown with one subunit of YnaI (purple). Residues at the narrowest positions along the pathway are labeled and shown with side chains. b, c Zoomed-in views of these critical residues: L154, M158, and K161 rings (top view), as well as the aromatic ones around the side portal (side view), shown with corresponding densities (gray). d sliced top view of the cytosolic vestibule colored by coulombic surface charge computed in Chimera using default settings. Q280 and D283 are indicated by black circles.
