The Sam46 genome map visualized with BRIG software v.0.95 (http://brig.sourceforge.net). The inner ring shows the level of Sam112 genomic identity (tBLASTx e-value significance) to Sam46, from unrelated (white regions) to closely related (dark brown), according to the legend. Fuchsia arrow in Sam46 genome indicates the HNH-endonuclease absent in Sam112.
