Figure 2.
Superoperonal photosynthetic gene cluster of Rfx. antarcticus ANT.BRT. The puc genes, which are absent from Rhodobacter capsulatus, are present in the Rfx. antarcticus cluster. Lines indicate rearrangements in gene synteny and arrows indicate inversions. Color key: green, bacteriochlorophyll synthesis (bch); orange, carotenoid synthesis (crt); pink, photosynthetic reaction centers (puh); light-harvesting complexes (puf and puc); teal, regulatory proteins; white, uncharacterized proteins; black, hypothetical proteins. All other colors are unique for clarity.
