Table 6. A. Phylogenetic conservation of ATP6 in a ten amino acid window about I60N. Light shading shows amino acids found in
other mammals at greater than 1% frequency. Dark shading indicates bison sequence (not always the highest frequency)>The
neighborhood of I60N exhibits variable levels of conservation and no overt periodicity. The structure of the loop region containing
I60N is thus not constrained by available data. B. Alignment against the only homologous protein with determined 3D structure (PDB
1C17|M from E. coli) is not informative in the I60N region so the effect of the asparagine substitution cannot be modeled.
