FIG. 4.
Amino acid sequence alignment. The deduced amino acid sequence of V. parahaemolyticus NorM (NorM VPARA) and the amino acid sequences of E. coli YdhE (YdhE ECOLI) and H. influenzae YdhE (YdhE HAEIN) are aligned. The numbers on both sides refer to the position of the nearest residue on each line. Asterisks and dots indicate residues in YdhE of E. coli that are identical and similar to those in NorM, respectively.
