a, Ribbon diagram of the CorA pentameric complex, viewed in the plane of the membrane. On the right is a single unit of the CorA channel highlighting the following structural features: Stalk helix and inner TM1 helix (turquoise), outer helix (dark blue) and willow helices (purple). These and the remaining 
-helices (red) and 
-sheets (yellow) are numbered according to the text. The membrane surface is indicated. b, View from the intracellular region. c, View from the periplasm. This and other figures were generated with the program PyMOL25, except where indicated.
