Extended Data Fig. 5: Ion densities.
From: Structure and function of the human mitochondrial MRS2 channel
a-b, Cryo-EM densities in the three ion binding sites for Mg2+ (a) and Ca2+ (b). Mg2+ and Ca2+ are shown as magenta and yellow spheres, respectively. c, Densities near the assigned Cl− binding site from Li et al. (EMD-35630 and EMD-35631). d, Densities near the two additional Mg2+ binding sites in the pore from Lai et al. (EMD-41624).
