The interrelationship between members of the PrsA family proteins used in the study (left) and between the members of the AmyE family used (right). The phylogenetic tree was based on the mature protein sequence excluding signal peptides and calculated with the Phylogeny.fr tools (http://www.phylogeny.fr/) [24]. Branch lengths are proportional to the divergence of the amino acid sequences within each tree
