a Eukaryotic F-ATPase subunits are indicated as M (mitochondrial) or C (chloroplast).

b Gene identification numbers are linked to the corresponding sequences in the NCBI protein database

c Active site residues are indicated indicated in boldface and colored as follows: conserved ion-binding acidic (Glu/Asp) residue - red; other Na+ ligands (see Fig. 3) are in purple.. The hydrophobic residue corresponding to Val63 of Ilyobacter tartaricus c subunit is shaded yellow. The conserved small (Pro, Gly, Ala, Ser) residue, corresponding to Pro28 of I. tartaricus c subunit (see text) is shaded green.

d Predicted cation specificity of the c/K subunit. Ions whose binding has been experimentally studied are shown in bold and colored as in Fig. 5.

e Sequences used to construct sequence logos (Fig. 4) are marked with Y.

f Subunits that have been used to assign cation specificity on Fig. 5 are marked with Y.
