Protein clusters for each poly-y-D-glutamic acid capsule operon gene. Each box represents a protein cluster identified by Roary for each poly-y-D-glutamic acid (PGA) capsule operon gene, represented by each column of protein cluster boxes. Shared protein clusters indicate a minimum of 95% shared nucleotide identity in the annotated sequences. Each strain/isolate is represented by a different color. The clock icon to the right of the genome ID indicates an archival isolate. The “T” superscript indicates the B. anthracis type strain. All other genomes are contemporary isolates. Isolates that received multiple annotations for the same gene which formed different protein clusters are annotated with the locus of the annotation in the genome assembly.
