(A) Maximum likelihood phylogram for YndE1, YndE2, and YndE3 of 20 strains of B. licheniformis as well as of B. cereus and B. subtilis. Bootstrap support values above 50% are indicated at the nodes; however, no bootstrap support values for nodes within the clades for the three B. licheniformis Ynd genes are given. GerLB, GerAB, and GerBB from B. anthracis, B. licheniformis, and B. subtilis, respectively, were used as the outgroups. (B) Amino acid sequence alignment of the Ynd B subunits encoded by the yndE3, yndE2, and yndE1 genes of B. licheniformis DSM13/ATCC 14580.
