FIG. 2.

Comparison of Hfq amino acid sequences from different Moraxellaceae by CLUSTAL W and visualized with BoxShade 3.2. Capital letters in the consensus sequence indicate conserved amino acids appearing in all aligned sequences. Lowercase letters indicate amino acids in at least two sequences. Amino acids shaded gray share the same polarity as the black-shaded ones, whereas amino acids with a white background differ in their polarity to black- and gray-shaded amino acids. Numbers indicate the amino acid position in the protein.
