Figure 1.

A sequence alignment of HbpS-like proteins colour-coded by sequence conservation (blue, lowest; red, highest). The predicted signal peptides (where appropriate) have been removed to improve the quality of the alignment. The following symbols are used in the ‘conserved’ alignment displayed at the bottom of the figure: ‘.’ weakly conserved, ‘:’ strongly conserved, ‘*’ absolutely conserved. This figure was generated from the sequence alignment performed by the package T-COFFEE (Notredame et al., 2000 ▶).
