FIGURE 9.17 The evolutionary conservation profiles of EcNhaA, NHA2 and NHE1 (a) The membrane topology of NHE1 (residues
126 e 505). The residues are coloured according to their conservation grades. (b) The evolutionary conservation profiles of NHA2, NhaA, and
NHE1 mapped on the crystal structure of NhaA. (Adapted from Landau et al., 2007 (a), and (b) from Schushan et al., 2010 . Reproduced with
