Figure 1.

Genomic arrangement for Rv1337 mycobacterial orthologs. Unique genome organization occurs for Rv1337 orthologs across the genus. mur1 was downstream and cysM upstream of the rhomboids (except M. marinum and MAC species). Colored block arrows: blue, cysM; green, rhomboid homologs; purple, mur1; black, rhomboid surrounding genes; white, pseudogene. White boxes indicate distances between rhomboids and upstream and downstream genes. Boxed (blue) are the species with similar arrangement for the rhomboids.
