Fig 5. Phylogenomic distribution of riboswitch regulated genes and operons involved in lysine biosynthesis and transport in all other phylum excluding Firmicutes and Gammaproteobacteria.

Filled shapes (circle for biosynthesis, square for transporters genes and star for lysine catabolic genes) indicate both the riboswitch and the gene are present; unfilled shapes indicate that the riboswitch is absent but the corresponding gene is present. Species highlighted in bold maroon color possess a riboswitch upstream to an operon containing multiple biosynthesis genes all of which are represented by filled circles.
