Figure 1.

Amino acid sequence alignment of SscA and the Yersinia chaperone SycD. Conserved alpha helical regions are denoted with blue bars. Alignment was performed with Clustal W software (http://www.ebi.ac.uk), alpha helix content was inferred from the published SycD crystal structure (PDB 2VGY) and from predictions made using SSpro8 [21].
